.SH DESCRIPTION
.rs
.sp
This is a convenience function for extracting a captured substring, identified
by name, into a given buffer. The arguments are:
.sp
  \fIcode\fP          Pattern that was successfully matched
  \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
  \fIbuffer\fP        Buffer to receive the string
  \fIbuffersize\fP    Size of buffer
.sp
The yield is the length of the substring, PCRE_ERROR_NOMEMORY if the buffer was
too small, or PCRE_ERROR_NOSUBSTRING if the string name is invalid.
