The first argument points to a compiled pattern. The number 31 of capturing parentheses within the pattern is used to compute the number of 32 pairs of offsets that are required in the match data block. These form the 33 "output vector" (ovector) within the match data block, and are used to identify 34 the matched string and any captured substrings. 35 </P> 36 <P> 37 The second argument points to a general context, for custom memory management, 38 or is NULL to use the same memory allocator as was used for the compiled 39 pattern. The result of the function is NULL if the memory for the block could 40 not be obtained. 41 </P> 42 <P> 43 There is a complete description of the PCRE2 native API in the 44 <a href="pcre2api.html"><b>pcre2api</b></a> 45 page and a description of the POSIX API in the 46 <a href="pcre2posix.html"><b>pcre2posix</b></a> 47 page. 48 <p> 49 Return to the <a href="index.html">PCRE2 index page</a>. 50 </p> 51
