@deftypefun {int} {gnutls_x509_crl_get_extension_data2} (gnutls_x509_crl_t @var{crl}, unsigned @var{indx}, gnutls_datum_t * @var{data})

@var{crl}: should contain a @code{gnutls_x509_crl_t}  type

@var{indx}: Specifies which extension OID to read. Use (0) to get the first one.

@var{data}: will contain the extension DER-encoded data

This function will return the requested by the index extension data in the

certificate revocation list.  The extension data will be allocated using

@code{gnutls_malloc()} .

Use @code{gnutls_x509_crt_get_extension_info()}  to extract the OID.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned,

otherwise a negative error code is returned.  If you have reached the

last extension available @code{GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE} 

will be returned.
