.SH DESCRIPTION
|
|
.rs
|
|
.sp
|
|
This is a convenience function for extracting a captured substring by name. The
|
|
arguments are:
|
|
.sp
|
|
\fIcode\fP Compiled pattern
|
|
\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
|
|
\fIstringptr\fP Where to put the string pointer
|
|
.sp
|
|
The memory in which the substring is placed is obtained by calling
|
|
\fBpcre_malloc()\fP. The yield of the function 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.
