NAME
       gnutls_session_supplemental_register - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_session_supplemental_register(gnutls_session_t session,
       const char * name, gnutls_supplemental_data_format_type_t type,
       gnutls_supp_recv_func recv_func, gnutls_supp_send_func send_func,
       unsigned flags);

ARGUMENTS
       gnutls_session_t session
                   the session for which this will be registered

       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

       unsigned flags
                   must be zero

DESCRIPTION
       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.

SINCE
       3.5.5
