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.

        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.
