| 2 | NOTE: |
| 3 | I cannot get the vanilla getopt code to work (i.e. compile only what |
| 4 | is needed and not duplicate symbols found in the standard library) |
| 5 | on all the platforms that FLAC supports. In particular the gating |
| 6 | of code with the ELIDE_CODE #define is not accurate enough on systems |
| 7 | that are POSIX but not glibc. If someone has a patch that works on |
| 8 | GNU/Linux, Darwin, AND Solaris please submit it on the project page: |
| 9 | https://sourceforge.net/p/flac/patches/ |
| 10 | |
| 11 | In the meantime I have munged the global symbols and removed gates |
| 12 | around code, while at the same time trying to touch the original as |
| 13 | little as possible. |

| 79 | of `struct share__option' terminated by an element containing a name which is |
| 80 | zero. |
| 81 | |
| 82 | The field `has_arg' is: |
| 83 | share__no_argument (or 0) if the option does not take an argument, |
| 84 | share__required_argument (or 1) if the option requires an argument, |
| 85 | share__optional_argument (or 2) if the option takes an optional argument. |
| 86 | |
| 87 | If the field `flag' is not NULL, it points to a variable that is set |
| 88 | to the value given in the field `val' when the option is found, but |
| 89 | left unchanged if the option is not found. |
| 90 | |
| 91 | To have a long-named option do something other than set an `int' to |
| 92 | a compiled-in constant, such as set a value from `share__optarg', set the |
| 93 | option's `flag' field to zero and its `val' field to a nonzero |
| 94 | value (the equivalent single-letter option character, if there is |
| 95 | one). For long options that have a zero `flag' field, `share__getopt' |
| 96 | returns the contents of the `val' field. */ |
