SYNOPSIS
 

#include &#60;pcre2.h&#62;


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), excluding 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 allocation 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:
<pre>
 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
</pre>
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_ERROR_NOMEMORY if sufficient memory could not be obtained.
