NAME
gnutls_supplemental_register - API function

SYNOPSIS
#include <gnutls/gnutls.h>

int gnutls_supplemental_register(const char * name, gnutls_supplemental_data_format_type_t type, gnutls_supp_recv_func recv_func, gnutls_supp_send_func send_func);

ARGUMENTS

const char * name
    the name of the supplemental data to register

gnutls_supplemental_data_format_type_t type
    the type of the supplemental data format

gnutls_supp_recv_func recv_func
    the function to receive the data

gnutls_supp_send_func send_func
    the function to send the data

DESCRIPTION
This function will register a new supplemental data type (rfc4680). The registered data will remain until gnutls_global_deinit() is called. 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.

This function is not thread safe. As supplemental data are not defined under TLS 1.3, this function will disable TLS 1.3 support globally.

RETURNS
GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE
3.4.0
