/*
 * cn --C to NeWS example program
 *
 * This program shows input to a C program through a network window
 * under NeWS. Three types of input are illustrated: mouse (scaled to
 * window co-ordinates), menu (returns int), and keyboard (keyboard
 * input is edited and buffered and echoed in the NeWS server. The
 * input string is "flushed" to the C client in a single packet
 * on a <CR>).
