PCRE - Perl-compatible regular expressions
SYNOPSIS
#include <pcre.h>
int pcre_copy_substring(const char *subject, int *ovector,
int stringcount, int stringnumber, char *buffer,
int buffersize);
DESCRIPTION
This is a convenience function for extracting a captured substring into
a given buffer. The arguments are:
subject Subject that has been successfully matched
ovector Offset vector that pcre_exec() used
stringcount Value returned by pcre_exec()
stringnumber Number of the required substring
buffer Buffer to receive the string
buffersize Size of buffer
The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buf‐
fer was too small, or PCRE_ERROR_NOSUBSTRING if the string number is
invalid.
There is a complete description of the PCRE native API in the pcreapi
page and a description of the POSIX API in the pcreposix page.
