In Basic Signal Handling, we gave an example of establishing a simple handler for termination signals using signal . Here is an equivalent example using sigaction : #include <signal.h> void termination_handler (int,#include<stdio.h>. #include<signal.h>. void sigHandlerFunc(int sig);. int main(). struct sigaction saStruct;. sigemptyset(&saStruct.sa_mask);. saStruct.sa_flags = 0;. saStruct.sa_handler = sigHandlerFunc;. sigaction(SIGUSR1, &saStruct,,SIGFPE, 1, Arithmetic exceptions that are not masked, for example, overflow, division by zero, and incorrect operation. SIGHUP, 1, A controlling terminal is suspended, or the controlling process ended. SIGILL, 1, Detection of an incorrect function image. ,If oact is a NULL pointer, sigaction() does not store this information. The sigaction() function uses structures of the sigaction type. The following is an example of a sigaction() structure: struct sigaction void (*sa_handler)(int); sigset_t sa_mask; in,#include <stdio.h> #include <stdlib.h> #include <signal.h> #include <unistd.h> // This function will handle a signal. void HandleSignal(int sig, siginfo_t *si, void *context); int main(int argc, char *argv[]) struct sigaction sVal,[email protected]. * http://aspyct.org. * @aspyct (twitter). *. * Hope it helps :) */. #include <stdio.h>. #include <stdlib.h>. #include <signal.h> // sigaction(), sigsuspend(), sig*(). #include <unistd.h> // alarm(). void hand
