PCRE_GET_NAMED_SUBSTRING(3)PCRE_GET_NAMED_SUBSTRING(3)NAME
PCRE - Perl-compatible regular expressions
SYNOPSIS
#include <pcre.h>
int pcre_get_named_substring(const pcre *code,
const char *subject, int *ovector,
int stringcount, const char *stringname,
const char **stringptr);
DESCRIPTION
This is a convenience function for extracting a captured substring by
name. The arguments are:
code Compiled pattern
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
stringptr Where to put the string pointer
The memory in which the substring is placed is obtained by calling
pcre_malloc(). The yield of the function is the length of the extracted
substring, PCRE_ERROR_NOMEMORY if sufficient memory could not be
obtained, 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.
