SYNOPSIS

#include <pcre.h>

int pcre_get_substring_list(const char *subject, int *ovector, int stringcount, const char ***listptr);
int pcre16_get_substring_list(PCRE_SPTR16 subject, int *ovector, int stringcount, PCRE_SPTR16 **listptr);
int pcre32_get_substring_list(PCRE_SPTR32 subject, int *ovector, int stringcount, PCRE_SPTR32 **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[16|32]_exec used
      stringcount   Value returned by pcre[16|32]_exec
      listptr       Where to put a pointer to the list

The memory in which the substrings and the list are placed is obtained by calling pcre[16|32]_malloc(). The convenience function pcre[16|32]_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.

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.
