Otherwise, when both pointers have been set, the yield of the function is the length of each entry in code units. If the name is not found, PCRE2_ERROR_NOSUBSTRING is returned. </P> <P> There is a complete description of the PCRE2 native API, including the format of the table entries, in the <a href="pcre2api.html"><b>pcre2api</b></a> page, and a description of the POSIX API in the <a href="pcre2posix.html"><b>pcre2posix</b></a> page. <p> Return to the <a href="index.html">PCRE2 index page</a>. </p>
