PCRE - Perl-compatible regular expressions

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]_execlistptr       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.
