Tt_status tttk_message_reject( Tt_message msg, Tt_status status, const char* status_string, int destroy};
The tttk_message_reject() function rejects the message msg and then destroys it.
A program should abandon a message when it does not understand the message and wants to dispose of it.
A message whose state is TT_SENT can be rejected. If the message is not a handler-addressed message, or if it has a tt_message_status other than TT_WRN_START_MESSAGE, it can be rejected.
This function returns TT_DESKTOP_ENOTSUP.
