The arguments are: <pre> <i>match_data</i> The match data block for the match <i>name</i> Name of the required substring <i>buffer</i> Buffer to receive the string <i>bufflen</i> Length of buffer (code units) </pre> The <i>bufflen</i> variable is updated to contain the length of the extracted string, excluding the trailing zero. The yield of the function is zero for success or one of the following error numbers: <pre> PCRE2_ERROR_NOSUBSTRING there are no groups of that name PCRE2_ERROR_UNAVAILBLE the ovector was too small for that group PCRE2_ERROR_UNSET the group did not participate in the match PCRE2_ERROR_NOMEMORY the buffer is not big enough </pre> If there is more than one group with the given name, the first one that is set is returned. In this situation PCRE2_ERROR_UNSET means that no group with the given name was set. </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>
