<H2>DESCRIPTION</H2>
<P>
This is a convenience function for extracting a list of all the captured
substrings. The arguments are:
<P>
<BR>&nbsp;&nbsp;<I>subject</I>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subject&nbsp;that&nbsp;has&nbsp;been&nbsp;successfully&nbsp;matched
<BR>&nbsp;&nbsp;<I>ovector</I>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Offset&nbsp;vector&nbsp;that&nbsp;<B>pcre[16|32]_exec</B>&nbsp;used
<BR>&nbsp;&nbsp;<I>stringcount</I>&nbsp;&nbsp;&nbsp;Value&nbsp;returned&nbsp;by&nbsp;<B>pcre[16|32]_exec</B>
<BR>&nbsp;&nbsp;<I>listptr</I>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Where&nbsp;to&nbsp;put&nbsp;a&nbsp;pointer&nbsp;to&nbsp;the&nbsp;list
<P>
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.
<P>
There is a complete description of the PCRE native API in the
<B>pcreapi</B>
page and a description of the POSIX API in the
<B>pcreposix</B>
page.
