26 This is a convenience function for extracting a captured substring. The
29 \fIsubject\fP Subject that has been successfully matched
30 \fIovector\fP Offset vector that \fBpcre[16|32]_exec()\fP used
31 \fIstringcount\fP Value returned by \fBpcre[16|32]_exec()\fP
32 \fIstringnumber\fP Number of the required substring
33 \fIstringptr\fP Where to put the string pointer
35 The memory in which the substring is placed is obtained by calling
36 \fBpcre[16|32]_malloc()\fP. The convenience function
37 \fBpcre[16|32]_free_substring()\fP can be used to free it when it is no longer
38 needed. The yield of the function is the length of the substring,
39 PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or
40 PCRE_ERROR_NOSUBSTRING if the string number is invalid.
