Add getopt supporting unicode Fixes #1191
2023-04-30 02:06:27 +02:00
/* Getopt for Microsoft C
This code is a modification of the Free Software Foundation, Inc.
Getopt library for parsing command line argument the purpose was
to provide a Microsoft Visual C friendly derivative. This code
provides functionality for both Unicode and Multibyte builds.
Date: 02/03/2011 - Ludvik Jerabek - Initial Release
Version: 1.1
Comment: Supports getopt, getopt_long, and getopt_long_only
and POSIXLY_CORRECT environment flag
License: LGPL
Revisions:
02/03/2011 - Ludvik Jerabek - Initial Release
02/20/2011 - Ludvik Jerabek - Fixed compiler warnings at Level 4
07/05/2011 - Ludvik Jerabek - Added no_argument, required_argument, optional_argument defs
08/03/2011 - Ludvik Jerabek - Fixed non-argument runtime bug which caused runtime exception
08/09/2011 - Ludvik Jerabek - Added code to export functions for DLL and LIB
02/15/2012 - Ludvik Jerabek - Fixed _GETOPT_THROW definition missing in implementation file
08/01/2012 - Ludvik Jerabek - Created separate functions for char and wchar_t characters so single dll can do both unicode and ansi
10/15/2012 - Ludvik Jerabek - Modified to match latest GNU features
06/19/2015 - Ludvik Jerabek - Fixed maximum option limitation caused by option_a (255) and option_w (65535) structure val variable
09/24/2022 - Ludvik Jerabek - Updated to match most recent getopt release
09/25/2022 - Ludvik Jerabek - Fixed memory allocation (malloc call) issue for wchar_t*
