Set up a handler for signal SIGABRT, such that it is called if 12 * signal is ever raised. 13 * 2. Call sighold on that SIGABRT. 14 * 3. Raise a SIGABRT and verify that the signal handler was not called. 15 * Otherwise, the test exits with unresolved results. 16 * 4. Call sigrelse on SIGABRT. 17 * 5. Verify that the handler gets called this time. 18 */ 19 20 #include <signal.h> 21 #include <stdio.h> 22 #include <unistd.h> 23 #include "posixtest.h" 24 25 static int handler_called; 26 handler(int signo)27static void handler(int signo) 28 { 29 handler_called = 1; 30 } 31 main(void)32int main(void) 33 { 34 struct sigaction act; 35 36 act.sa_handler = handler; 37 act.sa_flags = 0; 38 sigemptyset(&act.sa_mask); 39 if (sigaction(SIGABRT, &act, 0) == -1) { 40 perror("Failed to set signal handler."); 41 return PTS_UNRESOLVED; 42 } 43 44 sighold(SIGABRT); 45 46 if (raise(SIGABRT) == -1) { 47 perror("Failed to raise SIGABRT."); 48 return PTS_UNRESOLVED; 49 } 50 51 if (handler_called) { 52 printf("UNRESOLVED. possible problem in sigrelse\n"); 53 return PTS_UNRESOLVED; 54 } 55 56 if (sigrelse(SIGABRT) == -1) { 57 printf("UNRESOLVED. possible problem in sigrelse\n"); 58 return PTS_UNRESOLVED; 59 } 60 61 usleep(100000); 62 63 if (handler_called) { 64 printf("Test PASSED: SIGABRT removed from signal mask\n"); 65 return PTS_PASS; 66 } 67 printf("Test FAILED\n"); 68 return PTS_FAIL; 69 } 70
