DESCRIPTION

						|
</b><br>
 | 
						|
<P>
 | 
						|
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
 | 
						|
<b>pcre2_substring_list_free()</b> can be used to free it when it is no longer
 | 
						|
needed. The arguments are:
 | 
						|
<pre>
 | 
						|
  <i>match_data</i>    The match data block
 | 
						|
  <i>listptr</i>       Where to put a pointer to the list
 | 
						|
  <i>lengthsptr</i>    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
 | 
						|
<i>listptr</i>. The list is terminated by a NULL pointer. If <i>lengthsptr</i> is
 | 
						|
not NULL, a matching list of lengths is created, and its address is placed in
 | 
						|
<i>lengthsptr</i>. The yield of the function is zero on success or
 | 
						|
PCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained.
