Set up a signal handler for the signal that says we have caught the 12 * signal. 13 * 2. Call killpg on the current process group id, raising the signal. 14 * 3. If signal handler was called, test passed. 15 16 */ 17 18 #define SIGTOTEST SIGCHLD 19 20 #include <signal.h> 21 #include <stdio.h> 22 #include <stdlib.h> 23 #include <unistd.h> 24 #include "posixtest.h" 25 handler(int signo)26void handler(int signo) 27 { 28 (void) signo; 29 30 printf("Caught signal being tested!\n"); 31 printf("Test PASSED\n"); 32 _exit(PTS_PASS); 33 } 34 main(void)35int main(void) 36 { 37 int pgrp; 38 struct sigaction act; 39 40 act.sa_handler = handler; 41 act.sa_flags = 0; 42 if (sigemptyset(&act.sa_mask) == -1) { 43 perror("Error calling sigemptyset\n"); 44 return PTS_UNRESOLVED; 45 } 46 if (sigaction(SIGTOTEST, &act, 0) == -1) { 47 perror("Error calling sigaction\n"); 48 return PTS_UNRESOLVED; 49 } 50 51 if ((pgrp = getpgrp()) == -1) { 52 printf("Could not get process group number\n"); 53 return PTS_UNRESOLVED; 54 } 55 56 if (killpg(pgrp, SIGTOTEST) != 0) { 57 printf("Could not raise signal being tested\n"); 58 return PTS_UNRESOLVED; 59 } 60 61 printf("Should have exited from signal handler\n"); 62 printf("Test FAILED\n"); 63 return PTS_FAIL; 64 } 65
