- /* 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: 1.0
- 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
