The Fn getuid system call returns the real user ID of the calling process. The Fn geteuid system call returns the effective user ID of the calling process.The real user ID is that of the user who has invoked the program. As the effective user ID gives the process additional permissions during execution of ``set-user-ID '' mode processes, Fn getuid is used to determine the real-user-id of the calling process.
