Abstract: In accordance with a method and apparatus for synchronizing information browsing among multiple systems, a bridgeport system receives identifiers for data requests received in a first hardware system and automatically transmits the identifier of the requested data to one or more additional hardware systems. Each of these one or more additional hardware systems then retrieves the identified data, thereby keeping the data being provided in these hardware systems in synchronization.

Abstract: In accordance with a method and appatatus for synchronization information browsing among multiple systems, a bridgeport system receives identifiers for data requests received in a first hardware system and automatically transmits the identifier of the requested data to one or more additional hardware systems. Each of these one or more additional hardware systems then retrieves the identified data, thereby keeping the data being provided in these hardware systems in synchronization.

Abstract: A method for notifying a client application program of an event in a shared application program in a computer system is disclosed. A client application program executing in the computer system registers a callback function during startup. The shared application program senses the event and maps the event to one of a set of registered client application programs. The callback function of the appropriate client application program is then invoked such that the callback function passes parameters for the event to the client application program.
