@deftypefun {int} {gnutls_x509_crl_get_number} (gnutls_x509_crl_t @var{crl}, void * @var{ret}, size_t * @var{ret_size}, unsigned int * @var{critical})
@var{crl}: should contain a @code{gnutls_x509_crl_t}  structure

@var{ret}: The place where the number will be copied

@var{ret_size}: Holds the size of the result field.

@var{critical}: will be non (0) if the extension is marked as critical
(may be null)

This function will return the CRL number extension.  This is
obtained by the CRL Number extension field (2.5.29.20).

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error code in case of an error.

@strong{Since:} 2.8.0
