The editor makes use of control characters for doing various things, including things like DEL and Control-\ which normally send interrupts. In order to get one character at a time, I do the following: (echo is previously turned off, using the noecho() call.) raw(); c = getchar(); noraw(); c &= 0177; /* lop off parity bit */ return(c); The problem when I do this is that I lose all type ahead when the editor is redrawing the screen or searching or such. My question then is, how can I continue to do raw I/O for the control characters, but keep the type-ahead? I know it's possible, becuase VI does it.
