+ The 'zlib' compression library provides in-memory compression and
+ decompression functions, including integrity checks of the uncompressed data.
+ This version of the library supports only one compression method (deflation)
+ but other algorithms will be added later and will have the same stream
+ interface.
+
+ Compression can be done in a single step if the buffers are large enough,
+ or can be done by repeated calls of the compression function. In the latter
+ case, the application must provide more input and/or consume the output
+ (providing more output space) before each call.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio using the functions that start
+ with "gz". The gzip format is different from the zlib format. gzip is a
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+ This library can optionally read and write gzip streams in memory as well.
+
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never crash
+ even in case of corrupted input.

+/*
+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary (in interactive applications). Some
+ output may be provided even if flush is not set.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating avail_in or avail_out accordingly; avail_out should
+ never be zero before the call. The application can consume the compressed
+ output when it wants, for example when the output buffer is full (avail_out
+ == 0), or after each call of deflate(). If deflate returns Z_OK and with
+ zero avail_out, it must be called again after making room in the output
+ buffer because there might be more output pending.
+
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+ decide how much data to accumulate before producing output, in order to
+ maximize compression.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In
+ particular avail_in is zero after the call if enough output space has been
+ provided before the call.) Flushing may degrade compression for some
+ compression algorithms and so it should be used only when necessary. This
+ completes the current deflate block and follows it with an empty stored block
+ that is three bits plus filler bits to the next byte, followed by four bytes
+ (00 00 ff ff).
+
+ If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+ output buffer, but the output is not aligned to a byte boundary. All of the
+ input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+ This completes the current deflate block and follows it with an empty fixed
+ codes block that is 10 bits long. This assures that enough bytes are output
+ in order for the decompressor to finish the block before the empty fixed code
+ block.
+
+ If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+ for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+ seven bits of the current block are held to be written as the next byte after
+ the next deflate block is completed. In this case, the decompressor may not
+ be provided enough bits at this point in order to complete decompression of
+ the data provided so far to the compressor. It may need to wait for the next
+ block to be emitted. This is for advanced applications that need to control
+ the emission of deflate blocks.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ compression.
+
+ If deflate returns with avail_out == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+ avail_out is greater than six to avoid repeated flush markers due to
+ avail_out == 0 on return.
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,
+ pending output is flushed and deflate returns with Z_STREAM_END if there was
+ enough output space; if deflate returns with Z_OK, this function must be
+ called again with Z_FINISH and more output space (updated avail_out) but no
+ more input data, until it returns with Z_STREAM_END or an error. After
+ deflate has returned Z_STREAM_END, the only possible operations on the stream
+ are deflateReset or deflateEnd.
+
+ Z_FINISH can be used immediately after deflateInit if all the compression
+ is to be done in a single step. In this case, avail_out must be at least the
+ value returned by deflateBound (see below). Then deflate is guaranteed to
+ return Z_STREAM_END. If not enough output space is provided, deflate will
+ not return Z_STREAM_END, and it must be called again as described above.
+
+ deflate() sets strm->adler to the adler32 checksum of all input read
+ so far (that is, total_in bytes).
+
+ deflate() may update strm->data_type if it can make a good guess about
+ the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+ binary. This field is only for information purposes and does not affect the
+ compression algorithm in any manner.
+
+ deflate() returns Z_OK if some progress has been made (more input
+ processed or more output produced), Z_STREAM_END if all input has been
+ consumed and all output has been produced (only when flush is set to
+ Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+ if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
+ (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not
+ fatal, and deflate() can be called again with more input and more output

+ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush));
+/*
+ inflate decompresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. inflate performs one or both of the
+ following actions:
+
+ - Decompress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in is updated and processing will
+ resume at this point for the next call of inflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. inflate() provides as much output as possible, until there is
+ no more input data or no more space in the output buffer (see below about
+ the flush parameter).
+
+ Before the call of inflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating the next_* and avail_* values accordingly. The
+ application can consume the uncompressed output when it wants, for example
+ when the output buffer is full (avail_out == 0), or after each call of
+ inflate(). If inflate returns Z_OK and with zero avail_out, it must be
+ called again after making room in the output buffer because there might be
+ more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+ Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate()
+ stop if and when it gets to the next deflate block boundary. When decoding
+ the zlib or gzip format, this will cause inflate() to return immediately
+ after the header and before the first block. When doing a raw inflate,
+ inflate() will go ahead and process the first block, and will return when it
+ gets to the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64 if
+ inflate() is currently decoding the last block in the deflate stream, plus
+ 128 if inflate() returned immediately after decoding an end-of-block code or
+ decoding the complete header up to just before the first byte of the deflate
+ stream. The end-of-block will not be indicated until all of the uncompressed
+ data from that block has been written to strm->next_out. The number of
+ unused bits may in general be greater than seven, except when bit 7 of
+ data_type is set, in which case the number of unused bits will be less than
+ eight. data_type is set as noted here every time inflate() returns for all
+ flush options, and so can be used to determine the amount of currently
+ consumed input in bits.
+
+ The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+ end of each deflate block header is reached, before any actual data in that
+ block is decoded. This allows the caller to determine the length of the
+ deflate block header for later use in random access within a deflate block.
+ 256 is added to the value of strm->data_type when inflate() returns
+ immediately after reaching the end of the deflate block header.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step (a
+ single call of inflate), the parameter flush should be set to Z_FINISH. In
+ this case all pending input is processed and all pending output is flushed;
+ avail_out must be large enough to hold all of the uncompressed data for the
+ operation to complete. (The size of the uncompressed data may have been
+ saved by the compressor for this purpose.) The use of Z_FINISH is not
+ required to perform an inflation in one step. However it may be used to
+ inform inflate that a faster approach can be used for the single inflate()
+ call. Z_FINISH also informs inflate to not maintain a sliding window if the
+ stream completes, which reduces inflate's memory footprint. If the stream
+ does not complete, either because not all of the stream is provided or not
+ enough output space is provided, then a sliding window will be allocated and
+ inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+ been used.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the effects of the flush parameter in this implementation are
+ on the return value of inflate() as noted below, when inflate() returns early
+ when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+ memory for a sliding window when Z_FINISH is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the Adler-32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically, if requested when
+ initializing with inflateInit2(). Any information contained in the gzip
+ header is not retained, so applications that need that information should
+ instead use raw inflate, see inflateInit2() below, or inflateBack() and
+ perform their own processing of the gzip header and trailer. When processing
+ gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+ producted so far. The CRC-32 is checked against the gzip trailer.
+
+ inflate() returns Z_OK if some progress has been made (more input processed
+ or more output produced), Z_STREAM_END if the end of the compressed data has
+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+ preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+ corrupted (input stream not conforming to the zlib format or incorrect check
+ value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+ next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
+ Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+ output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
+ inflate() can be called again with more input and more output space to
+ continue decompressing. If Z_DATA_ERROR is returned, the application may
+ then call inflateSync() to look for a good compression block if a partial
+ recovery of the data is desired.

+
+ This is another version of deflateInit with more compression options. The
+ fields next_in, zalloc, zfree and opaque must be initialized before by the
+ caller.
+
+ The method parameter is the compression method. It must be Z_DEFLATED in
+ this version of the library.
+
+ The windowBits parameter is the base two logarithm of the window size
+ (the size of the history buffer). It should be in the range 8..15 for this
+ version of the library. Larger values of this parameter result in better
+ compression at the expense of memory usage. The default value is 15 if
+ deflateInit is used instead.
+
+ windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+ determines the window size. deflate() will then generate raw deflate data
+ with no zlib header or trailer, and will not compute an adler32 check value.
+
+ windowBits can also be greater than 15 for optional gzip encoding. Add
+ 16 to windowBits to write a simple gzip header and trailer around the
+ compressed data instead of a zlib wrapper. The gzip header will have no
+ file name, no extra data, no comment, no modification time (set to zero), no
+ header crc, and the operating system will be set to 255 (unknown). If a
+ gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+ The memLevel parameter specifies how much memory should be allocated
+ for the internal compression state. memLevel=1 uses minimum memory but is
+ slow and reduces compression ratio; memLevel=9 uses maximum memory for
+ optimal speed. The default value is 8. See zconf.h for total memory usage
+ as a function of windowBits and memLevel.
+
+ The strategy parameter is used to tune the compression algorithm. Use the
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+ string match), or Z_RLE to limit match distances to one (run-length
+ encoding). Filtered data consists mostly of small values with a somewhat
+ random distribution. In this case, the compression algorithm is tuned to
+ compress them better. The effect of Z_FILTERED is to force more Huffman
+ coding and less string matching; it is somewhat intermediate between
+ Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
+ fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
+ strategy parameter only affects the compression ratio but not the
+ correctness of the compressed output even if it is not set appropriately.
+ Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+ decoder for special applications.
+

+
+ The dictionary should consist of strings (byte sequences) that are likely
+ to be encountered later in the data to be compressed, with the most commonly

+ inflateBack() does a raw inflate with a single call using a call-back
+ interface for input and output. This is potentially more efficient than
+ inflate() for file i/o applications, in that it avoids copying between the
+ output and the sliding window by simply making the window itself the output
+ buffer. inflate() can be faster on modern CPUs when used with large
+ buffers. inflateBack() trusts the application to not change the output
+ buffer passed by the output function, at least until inflateBack() returns.
+
+ inflateBackInit() must be called first to allocate the internal state
+ and to initialize the state with the user-provided window buffer.
+ inflateBack() may then be used multiple times to inflate a complete, raw
+ deflate stream with each call. inflateBackEnd() is then called to free the
+ allocated state.
+
+ A raw deflate stream is one with no zlib or gzip header or trailer.
+ This routine would normally be used in a utility that reads zip or gzip
+ files and writes out uncompressed files. The utility would decode the
+ header and process the trailer on its own, hence this routine expects only
+ the raw deflate stream to decompress. This is different from the normal
+ behavior of inflate(), which expects either a zlib or gzip header and
+ trailer around the deflate stream.
+
+ inflateBack() uses two subroutines supplied by the caller that are then
+ called by inflateBack() for input and output. inflateBack() calls those
+ routines until it reads a complete deflate stream and writes out all of the
+ uncompressed data, or until it encounters an error. The function's
+ parameters and return types are defined above in the in_func and out_func
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the
+ number of bytes of provided input, and a pointer to that input in buf. If
+ there is no input available, in() must return zero--buf is ignored in that
+ case--and inflateBack() will return a buffer error. inflateBack() will call
+ out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
+ should return zero on success, or non-zero on failure. If out() returns
+ non-zero, inflateBack() will return with an error. Neither in() nor out()
+ are permitted to change the contents of the window provided to
+ inflateBackInit(), which is also the buffer that out() uses to write from.
+ The length written by out() will be at most the window size. Any non-zero
+ amount of input may be provided by in().
+
+ For convenience, inflateBack() can be provided input on the first call by
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then
+ in() will be called. Therefore strm->next_in must be initialized before
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
+ must also be initialized, and then if strm->avail_in is not zero, input will
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+ The in_desc and out_desc parameters of inflateBack() is passed as the
+ first parameter of in() and out() respectively when they are called. These
+ descriptors can be optionally used to pass any information that the caller-
+ supplied in() and out() functions need to do their job.
+
+ On return, inflateBack() will set strm->next_in and strm->avail_in to
+ pass back any unused input that was provided by the last in() call. The
+ return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+ if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+ in the deflate stream (in which case strm->msg is set to indicate the nature
+ of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+ In the case of Z_BUF_ERROR, an input or output error can be distinguished
+ using strm->next_in which will be Z_NULL only if in() returned an error. If
+ strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+ non-zero. (in() will always be called before out(), so strm->next_in is
+ assured to be defined if out() returns non-zero.) Note that inflateBack()

+ The 'zlib' compression library provides in-memory compression and
+ decompression functions, including integrity checks of the uncompressed data.
+ This version of the library supports only one compression method (deflation)
+ but other algorithms will be added later and will have the same stream
+ interface.
+
+ Compression can be done in a single step if the buffers are large enough,
+ or can be done by repeated calls of the compression function. In the latter
+ case, the application must provide more input and/or consume the output
+ (providing more output space) before each call.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio using the functions that start
+ with "gz". The gzip format is different from the zlib format. gzip is a
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+ This library can optionally read and write gzip streams in memory as well.
+
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never crash
+ even in case of corrupted input.

+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary (in interactive applications). Some
+ output may be provided even if flush is not set.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating avail_in or avail_out accordingly; avail_out should
+ never be zero before the call. The application can consume the compressed
+ output when it wants, for example when the output buffer is full (avail_out
+ == 0), or after each call of deflate(). If deflate returns Z_OK and with
+ zero avail_out, it must be called again after making room in the output
+ buffer because there might be more output pending.
+
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+ decide how much data to accumulate before producing output, in order to
+ maximize compression.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In
+ particular avail_in is zero after the call if enough output space has been
+ provided before the call.) Flushing may degrade compression for some
+ compression algorithms and so it should be used only when necessary. This
+ completes the current deflate block and follows it with an empty stored block
+ that is three bits plus filler bits to the next byte, followed by four bytes
+ (00 00 ff ff).
+
+ If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+ output buffer, but the output is not aligned to a byte boundary. All of the
+ input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+ This completes the current deflate block and follows it with an empty fixed
+ codes block that is 10 bits long. This assures that enough bytes are output
+ in order for the decompressor to finish the block before the empty fixed code
+ block.
+
+ If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+ for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+ seven bits of the current block are held to be written as the next byte after
+ the next deflate block is completed. In this case, the decompressor may not
+ be provided enough bits at this point in order to complete decompression of
+ the data provided so far to the compressor. It may need to wait for the next
+ block to be emitted. This is for advanced applications that need to control
+ the emission of deflate blocks.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ compression.
+
+ If deflate returns with avail_out == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+ avail_out is greater than six to avoid repeated flush markers due to
+ avail_out == 0 on return.
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,
+ pending output is flushed and deflate returns with Z_STREAM_END if there was
+ enough output space; if deflate returns with Z_OK, this function must be
+ called again with Z_FINISH and more output space (updated avail_out) but no
+ more input data, until it returns with Z_STREAM_END or an error. After
+ deflate has returned Z_STREAM_END, the only possible operations on the stream
+ are deflateReset or deflateEnd.
+
+ Z_FINISH can be used immediately after deflateInit if all the compression
+ is to be done in a single step. In this case, avail_out must be at least the
+ value returned by deflateBound (see below). Then deflate is guaranteed to
+ return Z_STREAM_END. If not enough output space is provided, deflate will
+ not return Z_STREAM_END, and it must be called again as described above.
+
+ deflate() sets strm->adler to the adler32 checksum of all input read
+ so far (that is, total_in bytes).
+
+ deflate() may update strm->data_type if it can make a good guess about
+ the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+ binary. This field is only for information purposes and does not affect the
+ compression algorithm in any manner.
+
+ deflate() returns Z_OK if some progress has been made (more input
+ processed or more output produced), Z_STREAM_END if all input has been
+ consumed and all output has been produced (only when flush is set to
+ Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+ if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
+ (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not

+ inflate decompresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. inflate performs one or both of the
+ following actions:
+
+ - Decompress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in is updated and processing will
+ resume at this point for the next call of inflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. inflate() provides as much output as possible, until there is
+ no more input data or no more space in the output buffer (see below about
+ the flush parameter).
+
+ Before the call of inflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating the next_* and avail_* values accordingly. The
+ application can consume the uncompressed output when it wants, for example
+ when the output buffer is full (avail_out == 0), or after each call of
+ inflate(). If inflate returns Z_OK and with zero avail_out, it must be
+ called again after making room in the output buffer because there might be
+ more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+ Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate()
+ stop if and when it gets to the next deflate block boundary. When decoding
+ the zlib or gzip format, this will cause inflate() to return immediately
+ after the header and before the first block. When doing a raw inflate,
+ inflate() will go ahead and process the first block, and will return when it
+ gets to the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64 if
+ inflate() is currently decoding the last block in the deflate stream, plus
+ 128 if inflate() returned immediately after decoding an end-of-block code or
+ decoding the complete header up to just before the first byte of the deflate
+ stream. The end-of-block will not be indicated until all of the uncompressed
+ data from that block has been written to strm->next_out. The number of
+ unused bits may in general be greater than seven, except when bit 7 of
+ data_type is set, in which case the number of unused bits will be less than
+ eight. data_type is set as noted here every time inflate() returns for all
+ flush options, and so can be used to determine the amount of currently
+ consumed input in bits.
+
+ The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+ end of each deflate block header is reached, before any actual data in that
+ block is decoded. This allows the caller to determine the length of the
+ deflate block header for later use in random access within a deflate block.
+ 256 is added to the value of strm->data_type when inflate() returns
+ immediately after reaching the end of the deflate block header.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step (a
+ single call of inflate), the parameter flush should be set to Z_FINISH. In
+ this case all pending input is processed and all pending output is flushed;
+ avail_out must be large enough to hold all of the uncompressed data for the
+ operation to complete. (The size of the uncompressed data may have been
+ saved by the compressor for this purpose.) The use of Z_FINISH is not
+ required to perform an inflation in one step. However it may be used to
+ inform inflate that a faster approach can be used for the single inflate()
+ call. Z_FINISH also informs inflate to not maintain a sliding window if the
+ stream completes, which reduces inflate's memory footprint. If the stream
+ does not complete, either because not all of the stream is provided or not
+ enough output space is provided, then a sliding window will be allocated and
+ inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+ been used.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the effects of the flush parameter in this implementation are
+ on the return value of inflate() as noted below, when inflate() returns early
+ when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+ memory for a sliding window when Z_FINISH is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the Adler-32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically, if requested when
+ initializing with inflateInit2(). Any information contained in the gzip
+ header is not retained, so applications that need that information should
+ instead use raw inflate, see inflateInit2() below, or inflateBack() and
+ perform their own processing of the gzip header and trailer. When processing
+ gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+ producted so far. The CRC-32 is checked against the gzip trailer.
+
+ inflate() returns Z_OK if some progress has been made (more input processed
+ or more output produced), Z_STREAM_END if the end of the compressed data has
+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+ preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+ corrupted (input stream not conforming to the zlib format or incorrect check
+ value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+ next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
+ Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+ output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
+ inflate() can be called again with more input and more output space to
+ continue decompressing. If Z_DATA_ERROR is returned, the application may
+ then call inflateSync() to look for a good compression block if a partial
+ recovery of the data is desired.

+ZEXTERN int ZEXPORT deflateInit2 OF((z_streamp strm,
+ int level,
+ int method,
+ int windowBits,
+ int memLevel,
+ int strategy));
+
+ This is another version of deflateInit with more compression options. The
+ fields next_in, zalloc, zfree and opaque must be initialized before by the
+ caller.
+
+ The method parameter is the compression method. It must be Z_DEFLATED in
+ this version of the library.
+
+ The windowBits parameter is the base two logarithm of the window size
+ (the size of the history buffer). It should be in the range 8..15 for this
+ version of the library. Larger values of this parameter result in better
+ compression at the expense of memory usage. The default value is 15 if
+ deflateInit is used instead.
+
+ windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+ determines the window size. deflate() will then generate raw deflate data
+ with no zlib header or trailer, and will not compute an adler32 check value.
+
+ windowBits can also be greater than 15 for optional gzip encoding. Add
+ 16 to windowBits to write a simple gzip header and trailer around the
+ compressed data instead of a zlib wrapper. The gzip header will have no
+ file name, no extra data, no comment, no modification time (set to zero), no
+ header crc, and the operating system will be set to 255 (unknown). If a
+ gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+ The memLevel parameter specifies how much memory should be allocated
+ for the internal compression state. memLevel=1 uses minimum memory but is
+ slow and reduces compression ratio; memLevel=9 uses maximum memory for
+ optimal speed. The default value is 8. See zconf.h for total memory usage
+ as a function of windowBits and memLevel.
+
+ The strategy parameter is used to tune the compression algorithm. Use the
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+ string match), or Z_RLE to limit match distances to one (run-length
+ encoding). Filtered data consists mostly of small values with a somewhat
+ random distribution. In this case, the compression algorithm is tuned to
+ compress them better. The effect of Z_FILTERED is to force more Huffman
+ coding and less string matching; it is somewhat intermediate between
+ Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
+ fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
+ strategy parameter only affects the compression ratio but not the
+ correctness of the compressed output even if it is not set appropriately.
+ Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+ decoder for special applications.
+
+ deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+ memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
+ method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is

+ options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH. The

+
+ The dictionary should consist of strings (byte sequences) that are likely
+ to be encountered later in the data to be compressed, with the most commonly
+ used strings preferably put towards the end of the dictionary. Using a

+ A raw deflate stream is one with no zlib or gzip header or trailer.
+ This routine would normally be used in a utility that reads zip or gzip
+ files and writes out uncompressed files. The utility would decode the
+ header and process the trailer on its own, hence this routine expects only
+ the raw deflate stream to decompress. This is different from the normal
+ behavior of inflate(), which expects either a zlib or gzip header and
+ trailer around the deflate stream.
+
+ inflateBack() uses two subroutines supplied by the caller that are then
+ called by inflateBack() for input and output. inflateBack() calls those
+ routines until it reads a complete deflate stream and writes out all of the
+ uncompressed data, or until it encounters an error. The function's
+ parameters and return types are defined above in the in_func and out_func
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the
+ number of bytes of provided input, and a pointer to that input in buf. If
+ there is no input available, in() must return zero--buf is ignored in that
+ case--and inflateBack() will return a buffer error. inflateBack() will call
+ out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
+ should return zero on success, or non-zero on failure. If out() returns
+ non-zero, inflateBack() will return with an error. Neither in() nor out()
+ are permitted to change the contents of the window provided to
+ inflateBackInit(), which is also the buffer that out() uses to write from.
+ The length written by out() will be at most the window size. Any non-zero
+ amount of input may be provided by in().
+
+ For convenience, inflateBack() can be provided input on the first call by
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then
+ in() will be called. Therefore strm->next_in must be initialized before
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
+ must also be initialized, and then if strm->avail_in is not zero, input will
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+ The in_desc and out_desc parameters of inflateBack() is passed as the
+ first parameter of in() and out() respectively when they are called. These
+ descriptors can be optionally used to pass any information that the caller-
+ supplied in() and out() functions need to do their job.
+
+ On return, inflateBack() will set strm->next_in and strm->avail_in to
+ pass back any unused input that was provided by the last in() call. The
+ return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+ if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+ in the deflate stream (in which case strm->msg is set to indicate the nature
+ of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+ In the case of Z_BUF_ERROR, an input or output error can be distinguished
+ using strm->next_in which will be Z_NULL only if in() returned an error. If
+ strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+ non-zero. (in() will always be called before out(), so strm->next_in is
+ assured to be defined if out() returns non-zero.) Note that inflateBack()
+ cannot return Z_OK.
