char * oid, unsigned indx, void * buf, size_t * buf_size, unsigned int
* critical);
ARGUMENTS
gnutls_x509_crq_t crq
should contain a gnutls_x509_crq_t type
const char * oid
holds an Object Identifier in a null terminated string
unsigned indx
In case multiple same OIDs exist in the extensions, this
specifies which to get. Use (0) to get the first one.
void * buf a pointer to a structure to hold the name (may be null)
size_t * buf_size

certificate. The extensions will be returned as binary data DER
encoded, in the provided buffer.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error code in case of an error. If the certificate does not contain
the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be
