A version of the getopt library for use with wide character strings.

A version of the getopt library for use with wide character strings.
|
||||
|
||||
This is simply the gnu getopt library, but converted for use with
|
||||
wchar_t instead of char. This is not usually useful since the argv
|
||||
array is always defined to be of type char**, but in fish, all
|
||||
internal commands use wide characters and hence this library is
|
||||
useful.

|

If you want to use this version of getopt in your program,
|
||||
download the fish sourcecode, available at <a
|
||||
href='http://ridiculousfish.com/shell/'>the fish homepage</a>. Extract
|
||||
the sourcode, copy wgetopt.c and wgetopt.h into your program
|
||||
directory, include wgetopt.h in your program, and use all the
|
||||
regular getopt functions, prefixing every function, global
|
||||
variable and structure with a 'w', and use only wide character
|
||||
strings. There are no other functional changes in this version of
|
||||
getopt besides using wide character strings.
