The Mach port for the new port. This parameter should originally be of type mach_port_t.
Specifies options for what to do with the underlying port rights when the
NSMachobject is invalidated or destroyed. For a list of constants, see Mach Port Rights.
Returns an initialized
NSMach object that uses
mach to send or receive messages. The returned object might be different than the original receiver
