From the main() function, create a new thread. Give the new thread a 13 a second to set up for receiving a signal, and to suspend itself using 14 sigpause(). 15 2. From the main() thread, send signal to new thread to make sigpause return. 16 3. Verify that sigpause returns -1 and sets errno to EINTR. 17 */ 18 19 #define _XOPEN_SOURCE 600 20 21 #include <pthread.h> 22 #include <stdio.h> 23 #include <signal.h> 24 #include <errno.h> 25 #include <unistd.h> 26 #include "posixtest.h" 27 28 #define SIGTOTEST SIGABRT 29 #define INTHREAD 0 30 #define INMAIN 1 31 32 static int result = 2; 33 static int sem = INTHREAD; 34 35 static void handler() 36 { 37 printf("signal was called\n"); 38 return; 39 } 40 41 static void *a_thread_func() 42 { 43 int return_value = 0; 44 struct sigaction act; 45 act.sa_flags = 0; 46 act.sa_handler = handler; 47 sigemptyset(&act.sa_mask); 48 sigaction(SIGTOTEST, &act, 0); 49 return_value = sigpause(SIGTOTEST); 50 if (return_value == -1) { 51 if (errno == EINTR) { 52 printf("Test PASSED: sigpause returned -1 " 53 "and set errno to EINTR\n"); 54 result = 0; 55 } else { 56 printf("Test FAILED: sigpause did not " 57 "set errno to EINTR\n"); 58 result = 1; 59 } 60 } else { 61 if (errno == EINTR) 62 printf("Test FAILED: sigpause did not return -1\n"); 63 64 printf("Test FAILED: sigpause did not set errno to EINTR\n"); 65 printf("Test FAILED: sigpause did not return -1\n"); 66 result = 1; 67 68 } 69 sem = INMAIN; 70 return NULL; 71 } 72 73 int main(void) 74 { 75 pthread_t new_th; 76 77 if (pthread_create(&new_th, NULL, a_thread_func, NULL) != 0) { 78 perror("Error creating thread\n"); 79 return PTS_UNRESOLVED; 80 } 81 82 sleep(1); 83 84 if (pthread_kill(new_th, SIGTOTEST) != 0) { 85 printf("Test UNRESOLVED: Couldn't send signal to thread\n"); 86 return PTS_UNRESOLVED; 87 } 88 89 while (sem == INTHREAD) 90 sleep(1); 91 92 if (result == 2) 93 return PTS_UNRESOLVED; 94 95 if (result == 1) 96 return PTS_FAIL; 97 98 printf("Test PASSED\n"); 99 return PTS_PASS; 100 } 101
