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.

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.
