- The ggeettuuiidd() function returns the real user ID of the calling process.
- The ggeetteeuuiidd() function returns the effective user ID of the calling pro-
- cess.
-
- 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 execu-
- tion of ``_s_e_t_-_u_s_e_r_-_I_D'' mode processes, ggeettuuiidd() is used to determine the
- real-user-id of the calling process.
-
- EERRRROORRSS
- The ggeettuuiidd() and ggeetteeuuiidd() functions are always successful, and no return
- value is reserved to indicate an error.
