The function arguments are: <pre> <i>code</i> Compiled regular expression <i>name</i> Name whose number is required </pre> The yield of the function is the number of the parenthesis if the name is found, or PCRE2_ERROR_NOSUBSTRING if it is not found. When duplicate names are allowed (PCRE2_DUPNAMES is set), if the name is not unique, PCRE2_ERROR_NOUNIQUESUBSTRING is returned. You can obtain the list of numbers with the same name by calling <b>pcre2_substring_nametable_scan()</b>. </P> <P> There is a complete description of the PCRE2 native API 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>
