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 list

The 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.

There is a complete description of the PCRE native API in the pcreapi(3) page and a description of the POSIX API in the pcreposix(3) page.
