+SYNOPSIS
+        int seteuid(string str)
+
+DESCRIPTION
+        Set effective uid to str. The calling object must be
+        privileged to do so by the master object. In most
+        installations it can always be set to the current uid of the
+        object, to the uid of the creator of the object file, or to 0.
+
+        Result is 0 the euid could not be changed, and non-0 if it
+        was changed.
+
+        When this value is 0, the current object's uid can be changed
+        by export_uid(), and only then.
+
+        If strict euid usage is enforced, objects with euid 0 cannot
+        load or clone other objects.
+
+HISTORY
+        Since 3.2.1@47, this efun is availabe only when using euids.
+        Since 3.2.7, this efun is always available.
