DESCRIPTION

27       This  function  will return the requested extension OID in the certifi‐

29       buffer.

32       account for the trailing null.

36       error  code is returned.  If you have reached the last extension avail‐
37       able GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
