Example

#include <stdio.h>
-#include <stdlib.h>
-#include <signal.h>
- 
-void signal_handler(int sig)
-{
-    printf("Received signal: %d\n", sig);
-}
- 
-int main(void)
-{
-    /* Install a signal handler. */
-    if (signal(SIGTERM, signal_handler) == SIG_ERR)
-    {
-        printf("Error while installing a signal handler.\n");
-        exit(EXIT_FAILURE);
-    }
- 
-    printf("Sending signal: %d\n", SIGTERM);
-    if (raise(SIGTERM) != 0)
-    {
-        printf("Error while raising the SIGTERM signal.\n");
-        exit(EXIT_FAILURE);
-    }
- 
-    printf("Exit main()\n");
-    return EXIT_SUCCESS;
-}

Output:

-
Sending signal: 15
-Received signal: 15
-Exit main()
