If the 13 handler_called variable is anything but 1, then fail, otherwise pass. 14 15 */ 16 17 #define _XOPEN_SOURCE 600 18 19 #include <signal.h> 20 #include <stdio.h> 21 #include <stdlib.h> 22 #include "posixtest.h" 23 24 int handler_called = 0; 25 myhandler(int signo)26void myhandler(int signo) 27 { 28 printf("SIGCHLD called.
