.SH NAME
PCRE - Perl-compatible regular expressions
.SH SYNOPSIS
.rs
.sp
.B #include <pcre.h>
.PP
.SM
.br
.B int pcre_get_named_substring(const pcre *\fIcode\fP,
.ti +5n
.B const char *\fIsubject\fP, int *\fIovector\fP,
.ti +5n
.B int \fIstringcount\fP, const char *\fIstringname\fP,
.ti +5n
.B const char **\fIstringptr\fP);
.
.SH DESCRIPTION
.rs
.sp
This is a convenience function for extracting a captured substring by name. The
arguments are:
.sp
\fIcode\fP Compiled pattern
\fIsubject\fP Subject that has been successfully matched
\fIovector\fP Offset vector that \fBpcre_exec()\fP used
\fIstringcount\fP Value returned by \fBpcre_exec()\fP
\fIstringname\fP Name of the required substring
\fIstringptr\fP Where to put the string pointer
.sp
The memory in which the substring is placed is obtained by calling
\fBpcre_malloc()\fP. The yield of the function is the length of the extracted
substring, PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or
PCRE_ERROR_NOSUBSTRING if the string name is invalid.
.P
There is a complete description of the PCRE native API in the

\fBpcreapi\fP

page and a description of the POSIX API in the
.\" HREF
\fBpcreposix\fP
