　晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</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 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.
