       int pcre_get_substring_list(const char *subject,
            int *ovector, int stringcount, const char ***listptr);


       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
       page and a description of the POSIX API in the pcreposix page.
