NAME
PCRE - Perl-compatible regular expressions
SYNOPSIS
#include <pcre.h>
int pcre_get_substring(const char *subject, int *ovector,
int stringcount, int stringnumber,
const char **stringptr);
DESCRIPTION
This is a convenience function for extracting a captured substring. 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
stringptr Where to put the string pointer
The memory in which the substring is placed is obtained by calling
pcre_malloc(). The convenience function pcre_free_substring() can
be used to free it when it is no longer needed. The yield of the function is
the length of the substring, PCRE_ERROR_NOMEMORY if sufficient memory could not
be obtained, 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.
