From the main() function, create a new thread. Give the new thread a 12 a second to set up for receiving a signal, and to suspend itself using 13 sigpause(). 14 2. Have main() send the signal indicated by SIGTOTEST to the new thread, 15 using pthread_kill(). After doing this, give the new thread a second 16 to get to the signal handler. 17 3. In the main() thread, if the handler_called variable wasn't set to 1, 18 then the test has failed, else it passed. 19 */ 20 21 #define _XOPEN_SOURCE 600 22 23 #include <pthread.h> 24 #include <stdio.h> 25 #include <signal.h> 26 #include <errno.h> 27 #include <unistd.h> 28 #include "posixtest.h" 29 30 #define SIGTOTEST SIGABRT 31 32 static int handler_called; 33 34 static void handler() 35 { 36 printf("signal was called\n"); 37 handler_called = 1; 38 return; 39 } 40 41 static void *a_thread_func() 42 { 43 struct sigaction act; 44 act.sa_flags = 0; 45 act.sa_handler = handler; 46 sigemptyset(&act.sa_mask); 47 sigaction(SIGTOTEST, &act, 0); 48 sighold(SIGTOTEST); 49 sigpause(SIGTOTEST); 50 return NULL; 51 } 52 53 int main(void) 54 { 55 pthread_t new_th; 56 57 if (pthread_create(&new_th, NULL, a_thread_func, NULL) != 0) { 58 perror("Error creating thread\n"); 59 return PTS_UNRESOLVED; 60 } 61 62 sleep(1); 63 64 if (pthread_kill(new_th, SIGTOTEST) != 0) { 65 printf("Test UNRESOLVED: Couldn't send signal to thread\n"); 66 return PTS_UNRESOLVED; 67 } 68 69 sleep(1); 70 71 if (handler_called != 1) { 72 printf("Test FAILED: signal wasn't removed from signal mask\n"); 73 return PTS_FAIL; 74 } 75 76 printf("Test PASSED\n"); 77 return PTS_PASS; 78 } 79
