.SH NAME
Tcl_StringMatch, Tcl_StringCaseMatch \- test whether a string matches a pattern
.SH SYNOPSIS
.nf
\fB#include <tcl.h>\fR
.sp
int
\fBTcl_StringMatch\fR(\fIstr\fR, \fIpattern\fR)
.sp
int
\fBTcl_StringCaseMatch\fR(\fIstr\fR, \fIpattern\fR, \fIflags\fR)
.SH ARGUMENTS
.AS "const char" *pattern
.AP "const char" *str in
String to test.
.AP "const char" *pattern in
Pattern to match against string.  May contain special
characters from the set *?\e[].
.AP int flags in
OR-ed combination of match flags, currently only \fBTCL_MATCH_NOCASE\fR.
0 specifies a case-sensitive search.

.SH DESCRIPTION
.PP
This utility procedure determines whether a string matches
a given pattern.  If it does, then \fBTcl_StringMatch\fR returns
1.  Otherwise \fBTcl_StringMatch\fR returns 0.  The algorithm
used for matching is the same algorithm used in the \fBstring match\fR
Tcl command and is similar to the algorithm used by the C-shell
for file name matching;  see the Tcl manual entry for details.
.PP
In \fBTcl_StringCaseMatch\fR, the algorithm is
the same, but you have the option to make the matching case-insensitive.
If you choose this (by passing \fBTCL_MATCH_NOCASE\fR), then the string and
pattern are essentially matched in the lower case.
