// XGetopt.cpp Version 1.2
//
// Author: Hans Dietrich
// hdietrich2@hotmail.com
//
// Description:
// XGetopt.cpp implements getopt(), a function to parse command lines.
//
// History
// Version 1.2 - 2003 May 17
// - Added Unicode support
//
// Version 1.1 - 2002 March 10
// - Added example to XGetopt.cpp module header
//
// This software is released into the public domain.
// You are free to use it in any way you like.
//
// This software is provided "as is" with no expressed
// or implied warranty. I accept no liability for any
// damage or loss of business that this software may cause.

//
// NAME
// getopt -- parse command line options
//
// SYNOPSIS
// int getopt(int argc, char *argv[], char *optstring)
//
// extern char *optarg;
// extern int optind;
//
// DESCRIPTION
// The getopt() function parses the command line arguments. Its
// arguments argc and argv are the argument count and array as
// passed into the application on program invocation. In the case
// of Visual C++ programs, argc and argv are available via the
// variables __argc and __argv (double underscores), respectively.
// getopt returns the next option letter in argv that matches a
// letter in optstring. (Note: Unicode programs should use
// __targv instead of __argv. Also, all character and string
// literals should be enclosed in _T( ) ).
//
// optstring is a string of recognized option letters; if a letter
// is followed by a colon, the option is expected to have an argument
// that may or may not be separated from it by white space. optarg
// is set to point to the start of the option argument on return from
// getopt.
//
// Option letters may be combined, e.g., "-ab" is equivalent to
// "-a -b". Option letters are case sensitive.
//
// getopt places in the external variable optind the argv index
// of the next argument to be processed. optind is initialized
// to 0 before the first call to getopt.
//
// When all options have been processed (i.e., up to the first
// non-option argument), getopt returns EOF, optarg will point
// to the argument, and optind will be set to the argv index of
// the argument. If there are no non-option arguments, optarg
// will be set to nullptr.
//
// The special option "--" may be used to delimit the end of the
// options; EOF will be returned, and "--" (and everything after it)
// will be skipped.
//
// RETURN VALUE
// For option letters contained in the string optstring, getopt
// will return the option letter. getopt returns a question mark (?)
// when it encounters an option letter not included in optstring.
// EOF is returned when processing is finished.
//
// BUGS
// 1) Long options are not supported.
// 2) The GNU double-colon extension is not supported.
// 3) The environment variable POSIXLY_CORRECT is not supported.
// 4) The + syntax is not supported.
// 5) The automatic permutation of arguments is not supported.
// 6) This implementation of getopt() returns EOF if an error is
// encountered, instead of -1 as the latest standard requires.
//
// EXAMPLE
// BOOL CMyApp::ProcessCommandLine(int argc, char *argv[])
// {
// int c;
//
// while ((c = getopt(argc, argv, _T("aBn:"))) != EOF)
// {
// switch (c)
// {
// case _T('a'):
// TRACE(_T("option a\n"));
// //
// // set some flag here
// //
// break;
//
// case _T('B'):
// TRACE( _T("option B\n"));
// //
// // set some other flag here
// //
// break;
//
// case _T('n'):
// TRACE(_T("option n: value=%d\n"), atoi(optarg));
// //
// // do something with value here
// //
// break;
//
// case _T('?'):
// TRACE(_T("ERROR: illegal option %s\n"), argv[optind-1]);
// return FALSE;
// break;
//
// default:
// TRACE(_T("WARNING: no handler for option %c\n"), c);
// return FALSE;
// break;
// }
// }
// //
// // check for non-option args here
// //
// return TRUE;
// }
