.SH SYNOPSIS
.rs
.sp
.B #include <pcre.h>
.PP
.SM
.br
.B int pcre_copy_substring(const char *\fIsubject\fP, int *\fIovector\fP,
.ti +5n
.B int \fIstringcount\fP, int \fIstringnumber\fP, char *\fIbuffer\fP,
.ti +5n
.B int \fIbuffersize\fP);
.
.SH DESCRIPTION
.rs
.sp
This is a convenience function for extracting a captured substring into a given
buffer. The arguments are:
.sp
\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
\fIstringnumber\fP Number of the required substring
\fIbuffer\fP Buffer to receive the string
\fIbuffersize\fP Size of buffer
.sp
The yield is the legnth of the string, PCRE_ERROR_NOMEMORY if the buffer was
too small, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
.P
There is a complete description of the PCRE native API in the
.\" HREF
\fBpcreapi\fP
.\"
