[Potential * false failure here if the timer cannot be deleted in time. However, * the timer expiration will be set large enough that this should not * be likely.] * - Sleep until the timer would have expired. * - If no signal was caught, PASS. Otherwise, FAIL. * * For this test, signal SIGTOTEST will be used, clock CLOCK_REALTIME * will be used. */ #include #include #include #include #include #include "posixtest.h" #define SIGTOTEST SIGALRM #define TIMERSEC 3 void handler(int signo) { printf("Should not have caught signal\n"); exit(PTS_FAIL); } int main(int argc, char *argv[]) { struct sigevent ev; struct sigaction act; timer_t tid; struct itimerspec its; ev.sigev_notify = SIGEV_SIGNAL; ev.sigev_signo = SIGTOTEST; act.sa_handler=handler; act.sa_flags=0; its.it_interval.tv_sec = 0; its.it_interval.tv_nsec = 0; its.it_value.tv_sec = TIMERSEC; its.it_value.tv_nsec = 0; if (sigemptyset(&act.sa_mask) == -1) { perror("Error calling sigemptyset\n"); return PTS_UNRESOLVED; } if (sigaction(SIGTOTEST, &act, 0) == -1) { perror("Error calling sigaction\n"); return PTS_UNRESOLVED; } if (timer_create(CLOCK_REALTIME, &ev, &tid) != 0) { perror("timer_create() did not return success\n"); return PTS_UNRESOLVED; } if (timer_settime(tid, 0, &its, NULL) != 0) { perror("timer_settime() did not return success\n"); return PTS_UNRESOLVED; } if (timer_delete(tid) != 0) { perror("timer_delete() did not return success\n"); return PTS_UNRESOLVED; } if (sleep(TIMERSEC) != 0) { printf("sleep() did not sleep full time\n"); return PTS_FAIL; } printf("Test PASSED\n"); return PTS_PASS; }
