DESCRIPTION
</b><br>
<P>
This is a convenience function for extracting a list of all the captured
substrings. The arguments are:
<pre>
<i>subject</i> Subject that has been successfully matched
<i>ovector</i> Offset vector that <b>pcre[16|32]_exec</b> used
<i>stringcount</i> Value returned by <b>pcre[16|32]_exec</b>
<i>listptr</i> Where to put a pointer to the list
</pre>
The memory in which the substrings and the list are placed is obtained by
calling <b>pcre[16|32]_malloc()</b>. The convenience function
<b>pcre[16|32]_free_substring_list()</b> 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 <i>listptr</i>. 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.
