__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern

SYNOPSIS

       #include <tcl.h>

       int
       Tcl_StringMatch(str, pattern)

       int
       Tcl_StringCaseMatch(str, pattern, flags)

ARGUMENTS

       const char *str (in)		 String to test.

       const char *pattern (in) 	 Pattern to match against string.  May contain special characters from the set *?[].

       int flags (in)			 OR-ed combination of match flags, currently only TCL_MATCH_NOCASE.  0 specifies a case-sensitive search.
_________________________________________________________________

DESCRIPTION

       This  utility  procedure  determines  whether  a  string  matches  a given pattern.  If it does, then Tcl_StringMatch returns 1.  Otherwise
       Tcl_StringMatch returns 0.  The algorithm used for matching is the same algorithm used in the string match Tcl command and  is  similar	to
       the algorithm used by the C-shell for file name matching;  see the Tcl manual entry for details.

       In  Tcl_StringCaseMatch,  the algorithm is the same, but you have the option to make the matching case-insensitive.  If you choose this (by
       passing TCL_MATCH_NOCASE), then the string and pattern are essentially matched in the lower case.
