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.

RETURNS

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE

       3.4.0
