It was generatedautomatically from the original man page. If there is any nonsense in it,please consult the man page, in case the conversion went wrong.<br><br><b>SYNOPSIS</b><br><P><b>#include <pcre2.h></b></P><P><b>int pcre2_substring_list_get(pcre2_match_data *<i>match_data</i>,</b><b>" PCRE2_UCHAR ***<i>listptr</i>, PCRE2_SIZE **<i>lengthsptr</i>);</b></P><br><b>DESCRIPTION</b><br><P>This is a convenience function for extracting all the captured substrings aftera pattern match. It builds a list of pointers to the strings, and (optionally)a second list that contains their lengths (in code units), excluding aterminating zero that is added to each of them. All this is done in a singleblock of memory that is obtained using the same memory allocation function thatwas 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 longerneeded. 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> isnot 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 orPCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained.</P><P>There is a complete description of the PCRE2 native API in the<a href="pcre2api.html"><b>pcre2api</b></a>page and a description of the POSIX API in the<a href="pcre2posix.html"><b>pcre2posix</b></a>page.<p>Return to the <a href="index.html">PCRE2 index page</a>.</p>
