of the SYSV curses facilities. The added features are the collapsing of arrow and function keysequences (as defined by termcap for the terminal) into symbolic code returns thus relieving the application of recognising multi-character key sequences. Other features are the capability to perform a timed wait for a key (good for when you are not sure if there is a keypress ready or not) and the capability for turning off the inter-key timeout when assembling multi-character function keys. this work was done by Julian Coleman <J.D.Coleman@newcastle.ac.uk> and blymn@baea.com.au (Brett Lymn). i'm just integrating it. thanks HEAPS guys!
