It builds a list of pointers to the strings, and (optionally) 31 a second list that contains their lengths (in code units), excluding a 32 terminating zero that is added to each of them. All this is done in a single 33 block of memory that is obtained using the same memory allocation function that 34 was used to get the match data block. The convenience function 35 <b>pcre2_substring_list_free()</b> can be used to free it when it is no longer 36 needed. The arguments are: 37 <pre> 38 <i>match_data</i> The match data block 39 <i>listptr</i> Where to put a pointer to the list 40 <i>lengthsptr</i> Where to put a pointer to the lengths, or NULL 41 </pre> 42 A pointer to a list of pointers is put in the variable whose address is in 43 <i>listptr</i>. The list is terminated by a NULL pointer. If <i>lengthsptr</i> is 44 not NULL, a matching list of lengths is created, and its address is placed in 45 <i>lengthsptr</i>. The yield of the function is zero on success or 46 PCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained. 47 </P> 48 <P> 49 There is a complete description of the PCRE2 native API in the 50 <a href="pcre2api.html"><b>pcre2api</b></a> 51 page and a description of the POSIX API in the 52 <a href="pcre2posix.html"><b>pcre2posix</b></a> 53 page. 54 <p> 55 Return to the <a href="index.html">PCRE2 index page</a>. 56 </p> 57
