@deftypefun {int} {gnutls_x509_crl_export} (gnutls_x509_crl_t @var{crl}, gnutls_x509_crt_fmt_t @var{format}, void * @var{output_data}, size_t * @var{output_data_size})
@var{crl}: Holds the revocation list

@var{format}: the format of output params. One of PEM or DER.

@var{output_data}: will contain a private key PEM or DER encoded

@var{output_data_size}: holds the size of output_data (and will
be replaced by the actual size of parameters)

This function will export the revocation list to DER or PEM format.

If the buffer provided is not long enough to hold the output, then
@code{GNUTLS_E_SHORT_MEMORY_BUFFER}  will be returned.

If the structure is PEM encoded, it will have a header
of "BEGIN X509 CRL".

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