42 system call sets the real,
43 effective and saved user IDs of the current process.
46 sets the real, effective and saved group IDs.
48 Privileged processes may set these IDs
50 Unprivileged processes are restricted
51 in that each of the new IDs must match one of the current IDs.
53 Passing -1 as an argument causes the corresponding value
60 The calling process was not privileged
61 and tried to change one or more IDs to a value
62 which was not the current real ID, the current effective ID
63 nor the current saved ID.
76 These system calls are not available on many platforms.
79 to support Linux binaries linked against GNU libc2.
81 These system calls first appeared in HP-UX.
