Overview
This function will register a new supplemental data type (rfc4680). The registered supplemental functions will be used for that specific session. The provided type must be an unassigned type in gnutls_supplemental_data_format_type_t.
If the type is already registered or handled by GnuTLS internally GNUTLS_E_ALREADY_REGISTERED will be returned.
As supplemental data are not defined under TLS 1.3, this function will disable TLS 1.3 support for the given session.
Returns
GNUTLS_E_SUCCESS on success, otherwise a negative error code.
