.SH NAME
PCRE - Perl-compatible regular expressions
.SH SYNOPSIS
.rs
.sp
.B #include <pcre.h>
.PP
.SM
.B int pcre_get_stringnumber(const pcre *\fIcode\fP,
.ti +5n
.B const char *\fIname\fP);
.
.SH DESCRIPTION
.rs
.sp
This convenience function finds the number of a named substring capturing
parenthesis in a compiled pattern. Its arguments are:
.sp
\fIcode\fP Compiled regular expression
\fIname\fP Name whose number is required
.sp
The yield of the function is the number of the parenthesis if the name is
found, or PCRE_ERROR_NOSUBSTRING otherwise. When duplicate names are allowed
(PCRE_DUPNAMES is set), it is not defined which of the numbers is returned by
\fBpcre_get_stringnumber()\fP. You can obtain the complete list by calling
\fBpcre_get_stringtable_entries()\fP.
