18.SH DESCRIPTION
19.rs
20.sp
21This is a convenience function for extracting a captured substring, identified
22by name, into a given buffer. The arguments are:
23.sp
24 \fIcode\fP Pattern that was successfully matched
25 \fIsubject\fP Subject that has been successfully matched
26 \fIovector\fP Offset vector that \fBpcre_exec()\fP used
27 \fIstringcount\fP Value returned by \fBpcre_exec()\fP
28 \fIstringname\fP Name of the required substring
29 \fIbuffer\fP Buffer to receive the string
30 \fIbuffersize\fP Size of buffer
31.sp
32The yield is the length of the substring, PCRE_ERROR_NOMEMORY if the buffer was
33too small, or PCRE_ERROR_NOSUBSTRING if the string name is invalid.
