.SH DESCRIPTION
|
||
|
|
.rs
|
||
|
|
.sp
|
||
|
|
This is a convenience function for extracting a captured substring. The
|
||
|
|
arguments are:
|
||
|
|
.sp
|
||
|
|
\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
|
||
|
|
\fIstringnumber\fP Number 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 substring,
|
||
|
|
PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or
|
||
|
|
PCRE_ERROR_NOSUBSTRING if the string number is invalid.
