Abstract
One embodiment of the present invention provides a system for facilitating replacement of a system call in an application with a customized function call. During operation, the system re-links the application's executable file with additional code or dynamically injects the additional code to the application's executable file during run time. The additional code can change a pointer in a table which indicates addresses of imported functions so that the pointer indicates an address of the customized function call.
