char * oid, unsigned indx, gnutls_datum_t * output, unsigned int *
critical);
ARGUMENTS
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
const char * oid
holds an Object Identified in null terminated string
unsigned indx
In case multiple same OIDs exist in the extensions, this
specifies which to send. Use (0) to get the first one.
gnutls_datum_t * output
will hold the allocated extension data
unsigned int * critical
will be non-zero if the extension is marked as critical

certificate. The extensions will be returned as binary data DER en-
coded, in the provided buffer.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative er-
ror code is returned. If the certificate does not contain the specified
extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
