Means and method for controlling input events in multi-processing computer systems.

摘要

A method of inputting to a program or virtual process information from an external source such as another independently running process of an I/O device. Information is transmitted to a program by means of events, which may be selectively retrieved from an event queue by the program. User input such as that from a keyboard or mouse-type device, is treated specially to insure that the input goes to the proper program in a multi-processing environment. A keyboard driver is included that has the capacity to use individual translation tables for each individual application program which is running. User input from user activated devices, such as a keyboard or mouse, are combined with input from other parts of the systems by an input funnel which insures that user input is routed to the proper destination. The input funnel operates in conjunction with a window manager to allow a user to type a sequence of keys which may be directed to several different programs which are running.
