+getppid(), Function, Implemented, SUSP Functionality
+@end example
+
+@section User Identification
+
+@subsection Get Real User Effective User Real Group and Effective Group IDs
+
+@example
+getuid(), Function, Implemented, SUSP Functionality
+geteuid(), Function, Implemented, SUSP Functionality
+getgid(), Function, Implemented, SUSP Functionality
+getegid(), Function, Implemented, SUSP Functionality
+@end example
+
+@subsection Set User and Group IDs
+
+@example
+setuid(), Function, Implemented, SUSP Functionality
+setgid(), Function, Implemented, SUSP Functionality
+@end example
+
+@subsection Get Supplementary Group IDs
+
+@example
+getgroups(), Function, Implemented, SUSP Functionality
