18.SH DESCRIPTION
19.rs
20.sp
21This is a convenience function for extracting a captured substring by name. The
22arguments are:
23.sp
24 \fIcode\fP Compiled pattern
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 \fIstringptr\fP Where to put the string pointer
30.sp
31The memory in which the substring is placed is obtained by calling
32\fBpcre_malloc()\fP. The convenience function \fBpcre_free_substring()\fP can
33be used to free it when it is no longer needed. The yield of the function is
34the length of the extracted substring, PCRE_ERROR_NOMEMORY if sufficient memory
35could not be obtained, or PCRE_ERROR_NOSUBSTRING if the string name is invalid.
