.SH DESCRIPTION
.rs
.sp
This is a convenience function for extracting a captured substring by name. The
arguments are:

  \fIcode\fR          Compiled pattern
  \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
  \fIstringname\fR    Name of the required substring
  \fIstringptr\fR     Where to put the string pointer

The yield 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.
