SYNOPSIS
#include <pcre.h>
int pcre_get_substring_list(const char *subject, int *ovector, int stringcount, const char ***listptr);
DESCRIPTION
This is a convenience function for extracting a list of all the captured substrings. The arguments are:
subject Subject that has been successfully matched ovector Offset vector that pcre_exec used stringcount Value returned by pcre_exec listptr Where to put a pointer to the listThe memory in which the substrings and the list are placed is obtained by calling pcre_malloc(). The convenience function pcre_free_substring_list() can be used to free it when it is no longer needed. A pointer to a list of pointers is put in the variable whose address is in listptr. The list is terminated by a NULL pointer. The yield of the function is zero on success or PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained.
