If both a= re added in one call which one is reported depends on their order; however if = they are added using 2 calls everything works as expected I.e. struct kevent kev[2]; ... kevent(kqueue, kev, 2, NULL, 0, NULL); and struct kevent kev[2]; ... kevent(kqueue, kev, 1, NULL, 0, NULL); kevent(kqueue, kev + 1, 1, NULL, 0, NULL);=20 do not give identical results. Simple test case is attached - expected result would be for test program to output at least one line saying: BothReadWrite received EVFILT_WRITE --=20 You are receiving this mail because: You are the assignee for the bug.=
