+GETUID(2)                 Minix Programmer's Manual                  GETUID(2)
+
+
+NAME
+     getuid, geteuid - get user identity
+
+SYNOPSIS
+     #include <sys/types.h>
+     #include <unistd.h>
+
+     uid_t getuid(void)
+     uid_t geteuid(void)
+
+DESCRIPTION
+     Getuid returns the real user ID  of  the  current  process,  geteuid  the
+     effective user ID.
+
+     The real user ID identifies the person who is logged in.   The  effective
+     user  ID  gives  the  process  additional permissions during execution of
+     "set-user-ID" mode processes, which use getuid  to  determine  the  real-
+     user-id of the process that invoked them.
+
+SEE ALSO
+     getgid(2), setuid(2).
