.TH PCRE 3
.SH NAME
PCRE - Perl-compatible regular expressions
.SH SYNOPSIS
.rs
.sp
.B #include <pcre.h>
.PP
.SM
.br
.B int pcre_get_substring(const char *\fIsubject\fR, int *\fIovector\fR,
.ti +5n
.B int \fIstringcount\fR, int \fIstringnumber\fR,
.ti +5n
.B const char **\fIstringptr\fR);
.SH DESCRIPTION
.rs
.sp
This is a convenience function for extracting a captured substring. The
arguments are:
\fIsubject\fR Subject that has been successfully matched
\fIovector\fR Offset vector that \fBpcre_exec()\fR used
\fIstringcount\fR Value returned by \fBpcre_exec()\fR
\fIstringnumber\fR Number of the required substring
\fIstringptr\fR Where to put the string pointer
The yield is the length of the substring, PCRE_ERROR_NOMEMORY if sufficient
memory could not be obtained, or PCRE_ERROR_NOSUBSTRING if the string number is
invalid.
There is a complete description of the PCRE API in the
.\" HREF
\fBpcreapi\fR
.\"
page.
