PCRE2_SUBSTRING_LIST_GET(3) Library Functions Manual PCRE2_SUBSTRING_LIST_GET(3)

NAME
     PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

     #include <pcre2.h>

     int pcre2_substring_list_get(pcre2_match_data *match_data,
       PCRE2_UCHAR ***listptr, PCRE2_SIZE **lengthsptr);

DESCRIPTION

     This  is  a convenience function for extracting all the captured substrings
     after a pattern match. It builds a list of pointers  to  the  strings,  and
     (optionally) a second list that contains their lengths (in code units), ex-
     cluding  a terminating zero that is added to each of them. All this is done
     in a single block of memory that is obtained using the same memory  alloca-
     tion  function  that  was used to get the match data block. The convenience
     function pcre2_substring_list_free() can be used to free it when it  is  no
     longer needed. The arguments are:

       match_data    The match data block
       listptr	     Where to put a pointer to the list
       lengthsptr    Where to put a pointer to the lengths, or NULL

     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.  If  lengthsptr  is  not
     NULL,  a  matching list of lengths is created, and its address is placed in
     lengthsptr. The yield of the function  is	zero  on  success  or  PCRE2_ER-
     ROR_NOMEMORY if sufficient memory could not be obtained.

     There  is	a  complete  description of the PCRE2 native API in the pcre2api
     page and a description of the POSIX API in the pcre2posix page.
