- .SH NAME
- Tcl_RegExpMatch \- Test whether a string matches a regular expression
- .SH SYNOPSIS
- .nf
- \fB#include <tcl.h>\fR
- .sp
- int
- \fBTcl_RegExpMatch\fR(\fIinterp\fR, \fIstring\fR, \fIregexp\fR)
- .SH ARGUMENTS
- .AS Tcl_Interp *interp
- .AP Tcl_Interp *interp in
- Tcl interpreter to use for error reporting.
- .AP char *string in
- String to test.
- .AP char *regexp in
- Regular expression to match against \fIstring\fR.
- .BE

- .SH DESCRIPTION
- .PP
- \fBTcl_RegExpMatch\fR determines whether its \fIstring\fR argument
- matches \fIregexp\fR, where \fIregexp\fR is interpreted
- as a regular expression using the same rules as for the
- \fBregexp\fR Tcl command.
- If there is a match then \fBTcl_RegExpMatch\fR returns 1.
- If there is no match then \fBTcl_RegExpMatch\fR returns 0.
- If an error occurs in the matching process (e.g. \fIregexp\fR
- is not a valid regular expression) then \fBTcl_RegExpMatch\fR
- returns \-1 and leaves an error message in \fIinterp->result\fR.

- .SH KEYWORDS
