gnutls_x509_crt_get_extension_data(3) cert, unsigned

DESCRIPTION
This function will return the requested extension data in the certifi-
cate. The extension data will be stored in the provided buffer.
Use gnutls_x509_crt_get_extension_info() to extract the OID and criti-
cal flag. Use gnutls_x509_crt_get_extension_by_oid() instead, if you
want to get data indexed by the extension OID rather than sequence.

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error code is returned. If you have reached the last extension avail-
able GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
