Specifies which extension OID to send. Use zero to get the first one.

output variable with critical flag, may be NULL.
This function will return the requested extension OID in
the certificate, and the critical flag for it. The extension
OID will be stored as a string in the provided buffer. Use
gnutls_x509_crq_get_extension_data
() to
extract the data.
If the buffer provided is not long enough to hold the
output, then *sizeof_oid
is updated and
GNUTLS_E_SHORT_MEMORY_BUFFER
will be returned.
On success, GNUTLS_E_SUCCESS is returned, otherwise a negative value in case of an error. If your have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
