Toolkit’s utility routines handle a plethora of actions essential to your application. The two most important are U_START and U_FINISH, which are used to initialize and shut down the Toolkit environment. Other utility routines handle such tasks as loading and manipulating windows, performing file I/O and channel maintenance, standardizing messages, and key mapping, among others.
