clearing out a user message

rtapi_print_msg (RTAPI_MSG_ERR, "AIR CYLINDER NOT SAFE"); will print this message to the screen

what C command will clear it?
Im looking to do something like this

if((data_reset)==1{
clear_message // pseudo made up command
}


Ive looked around the net and havent come up with much.Thanks

I think that is UI-specific.

Axis maps it to Ctrl-Space, so you could look at the Axis source for that.
