Oh, that's not what I was talking about. That's not a hole, it's an anonymous memory object. I guess that is the appropriate semantic to match vm_map, as Thomas says. I suppose if you need a real hole you could make an empty real memory object, e.g. default_pager_object_set_size to zero. > Do we really need actual holes, ie, invalid pages? Can we use > MACH_PORT_DEAD? I don't think you can send MACH_PORT_DEAD (you just receive it when a dead name you didn't already have was sent). The only simple interface for it I can think of is some kludge like offset=-1 when memobj=MACH_PORT_NULL. I seem to have a desire to have an interface for a hole without using a real memory object, but I can't think of a use for it. (But then, I can't really think of a use for zero-fill regions in a proxy object.) _______________________________________________ Bug-hurd mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-hurd
