Mach IPC
hey everyone,
I'm reading a tutorial on the Mach kernel principles, however, the port and port rights part are kind of confusing to me. I don't know if the book has typos or something but it seems a bit contradictory. It says that "ports, themselves, are not named. It is the port rights that are" and then it later says that "a port is specified by a port name", so how can a port have a port name if the ports themselves aren't named. If anyone can clarify this for me I would greatly appreciate it. Also just to be absolutely certain, is the "port' sort of like an endpoint while the "port right" is like a channel to that endpoint?
thanks in advance
