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
