Register signal SIGTOTEST with the handler myhandler 13 2. Block SIGTOTEST from the process 14 3. Raise the signal, causing it to be pending 15 4. Call sigwaitinfo() and verify that it returns the signal SIGTOTEST. 16 */ 17 18 #define _XOPEN_REALTIME 1 19 #define SIGTOTEST SIGUSR1 20 21 #include <signal.h> 22 #include <stdio.h> 23 #include <stdlib.h> 24 #include <unistd.h> 25 #include <sys/wait.h> 26 #include "posixtest.h" 27 myhandler(int signo PTS_ATTRIBUTE_UNUSED)28static void myhandler(int signo PTS_ATTRIBUTE_UNUSED) 29 { 30 printf("Inside handler\n"); 31 } 32 main(void)33int main(void) 34 { 35 36 struct sigaction act; 37 sigset_t pendingset, selectset; 38 39 act.sa_flags = 0; 40 act.sa_handler = myhandler; 41 42 sigemptyset(&pendingset); 43 sigemptyset(&selectset); 44 sigaddset(&selectset, SIGTOTEST); 45 sigemptyset(&act.sa_mask); 46 47 sigaction(SIGTOTEST, &act, 0); 48 sighold(SIGTOTEST); 49 raise(SIGTOTEST); 50 51 sigpending(&pendingset); 52 53 if (sigismember(&pendingset, SIGTOTEST) != 1) { 54 perror("SIGTOTEST is not pending\n"); 55 return PTS_UNRESOLVED; 56 } 57 58 if (sigwaitinfo(&selectset, NULL) != SIGTOTEST) { 59 perror("Call to sigwaitinfo() failed\n"); 60 return PTS_FAIL; 61 } 62 63 printf("Test PASSED\n"); 64 return PTS_PASS; 65 } 66
