actual size of oid.
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_crt_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 (zero) is returned, otherwise an error code is returned. If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
