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);

int pcre16_copy_named_substring(const pcre16 *code,
     PCRE_SPTR16 subject, int *ovector,
     int stringcount, PCRE_SPTR16 stringname,
     PCRE_UCHAR16 *buffer, int buffersize);

int pcre32_copy_named_substring(const pcre32 *code,
     PCRE_SPTR32 subject, int *ovector,
     int stringcount, PCRE_SPTR32 stringname,
     PCRE_UCHAR32 *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[16|32]_exec() used
stringcount Value returned by pcre[16|32]_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.
