/* 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

/* 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
