Abstract

This paper proposes a merit of hooking through comparison of hooking with snatch method for an error detection on multimedia collaboration environment. A snatch is a method which intercepts all GDI(Graphic Device Interface) event. GDI snatching method is an event communication of hardware oriented between application program and graphic device driver. A hooking is a method which intercepts a communication message between window processes. This paper explains a performance analysis of an error detection system running on multimedia collaboration environment using the rule-based DEVS(Discrete Event System Specification) modeling and simulation technique. DEVS formalism introduced by Zeigler(1976). In DEVS, a system has a time base, inputs, states, outputs, and functions. A merit of hooking method is described for error detection in an interval time.
