-Opens a FLAC decoder from the file at the given path.
-
-
-Parameters
-----------
-pFileName (in)
- The path of the file to open, either absolute or relative to the current directory.
-
-pAllocationCallbacks (in, optional)
- A pointer to application defined callbacks for managing memory allocations.
-
-
-Return Value
-------------
-A pointer to an object representing the decoder.
-
-
-Remarks
--------
-Close the decoder with drflac_close().
-
-
-Remarks
--------
-This will hold a handle to the file until the decoder is closed with drflac_close(). Some platforms will restrict the number of files a process can have open
-at any given time, so keep this mind if you have many decoders open at the same time.
