     Mach special port into the value referenced by attr to the port refer-
     enced by newport for a port value of which, as if the new process had
     called ttaasskksseettssppeecciiaallppoorrtt().

     The ppoossiixxssppaawwnnaattttrrsseetteexxcceeppttiioonnppoorrttssnnpp() function sets the Mach port to
     newport for a number of exception ports represented by the bitfield
     mask, and sets the new default behavior and default flavor, as if the new
     process had called ttaasskksseetteexxcceeppttiioonnppoorrttss().
