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.
