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