The first argument specifies the number of pairs of offsets 31that are required. These form the "output vector" (ovector) within the match 32data block, and are used to identify the matched string and any captured 33substrings when matching with <b>pcre2_match()</b>, or a number of different 34matches at the same point when used with <b>pcre2_dfa_match()</b>. There is 35always one pair of offsets; if <b>ovecsize</b> is zero, it is treated as one. 36</P> 37<P> 38The second argument points to a general context, for custom memory management, 39or is NULL for system memory management. The result of the function is NULL if 40the memory for the block could not be obtained. 41</P> 42<P> 43There is a complete description of the PCRE2 native API in the 44<a href="pcre2api.html"><b>pcre2api</b></a> 45page and a description of the POSIX API in the 46<a href="pcre2posix.html"><b>pcre2posix</b></a> 47page. 48<p> 49Return to the <a href="index.html">PCRE2 index page</a>. 50</p> 51
