NAME
PCRE - Perl-compatible regular expressions
SYNOPSIS
#include <pcre.h>
int pcre_copy_named_substring(const pcre *code,
const char *subject, int *ovector,
int stringcount, const char *stringname,
char *buffer, int buffersize);
DESCRIPTION
This is a convenience function for extracting a captured substring,
identified by name, into a given buffer. The arguments are:
code Pattern that was successfully matched
subject Subject that has been successfully matched
ovector Offset vector that pcre_exec() used
stringcount Value returned by pcre_exec()
stringname Name of the required substring
buffer Buffer to receive the string
buffersize Size of buffer
The yield is the length of the substring, PCRE_ERROR_NOMEMORY if the
buffer was too small, or PCRE_ERROR_NOSUBSTRING if the string name 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.
