The 41 arguments are: 42 <pre> 43 <i>subject</i> Subject that has been successfully matched 44 <i>ovector</i> Offset vector that <b>pcre[16|32]_exec()</b> used 45 <i>stringcount</i> Value returned by <b>pcre[16|32]_exec()</b> 46 <i>stringnumber</i> Number of the required substring 47 <i>stringptr</i> Where to put the string pointer 48 </pre> 49 The memory in which the substring is placed is obtained by calling 50 <b>pcre[16|32]_malloc()</b>. The convenience function 51 <b>pcre[16|32]_free_substring()</b> can be used to free it when it is no longer 52 needed. The yield of the function is the length of the substring, 53 PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or 54 PCRE_ERROR_NOSUBSTRING if the string number is invalid. 55 </P> 56 <P> 57 There is a complete description of the PCRE native API in the 58 <a href="pcreapi.html"><b>pcreapi</b></a> 59 page and a description of the POSIX API in the 60 <a href="pcreposix.html"><b>pcreposix</b></a> 61 page. 62 <p> 63 Return to the <a href="index.html">PCRE index page</a>. 64 </p> 65
