3 PCRE - Perl-compatible regular expressions
11 .B int pcre_copy_substring(const char *\fIsubject\fP, int *\fIovector\fP,
13 .B int \fIstringcount\fP, int \fIstringnumber\fP, char *\fIbuffer\fP,
15 .B int \fIbuffersize\fP);
20 This is a convenience function for extracting a captured substring into a given
21 buffer. The arguments are:
23 \fIsubject\fP Subject that has been successfully matched
24 \fIovector\fP Offset vector that \fBpcre_exec()\fP used
25 \fIstringcount\fP Value returned by \fBpcre_exec()\fP
26 \fIstringnumber\fP Number of the required substring
27 \fIbuffer\fP Buffer to receive the string
28 \fIbuffersize\fP Size of buffer
30 The yield is the legnth of the string, PCRE_ERROR_NOMEMORY if the buffer was
31 too small, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
