tcl_stringmatch
Tcl_StringMatch(3) Tcl Library Procedures Tcl_StringMatch(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern
SYNOPSIS
#include <tcl.h>
int
Tcl_StringMatch(string, pattern)
int
Tcl_StringCaseMatch(string, pattern, nocase)
ARGUMENTS
char *string (in) String to test.
char *pattern (in) Pattern to match against string. May contain special characters from the set *?[].
int nocase (in) Specifies whether the match should be done case-sensitive (0) or case-insensitive (1).
_________________________________________________________________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 nocase as 1), then the string and pattern are essentially matched in the lower case.
KEYWORDS
match, pattern, string
