@deftypefun {int} {gnutls_x509_crl_get_crt_serial} (gnutls_x509_crl_t @var{crl}, int @var{indx}, unsigned char * @var{serial}, size_t * @var{serial_size}, time_t * @var{t})
@var{crl}: should contain a @code{gnutls_x509_crl_t}  structure

@var{indx}: the index of the certificate to extract (starting from 0)

@var{serial}: where the serial number will be copied

@var{serial_size}: initially holds the size of serial

@var{t}: if non null, will hold the time this certificate was revoked

This function will retrieve the serial number of the specified, by
the index, revoked certificate.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value. and a negative error code on error.
