Hello everyone welcome back to Arizona Programming zone, today I will show you how to catch interruption signals on a Windows system and what you can do when such signals are sent to your application. Interruption signals are for example control-c, a break or shutdown event.
Its just for windows
Go through the logical flow and create a new one for yourself. If any problem in understanding the logical flow you can contact sadik.shaikh@extremehacking.org
Here is the code.
#include
#include
/*
*
*/
BOOL APE_ControlHandler(DWORD pControlType);
int main()
{
int lRetVal = 0;
// Register the event handler
SetConsoleCtrlHandler((PHANDLER_ROUTINE) APE_ControlHandler, TRUE);
while (1)
Sleep(100);
return(lRetVal);
}
/*
*
*/
BOOL APE_ControlHandler(DWORD pControlType)
{
switch(pControlType)
{
// Handle the CTRL-C signal.
case CTRL_C_EVENT:
Beep(500, 200);
printf(“Ctrl-C event : Starting depoisoning process”);
return(FALSE);
case CTRL_CLOSE_EVENT:
Beep(600, 200);
printf(“Ctrl-Close event : Starting depoisoning process”);
return(FALSE);
case CTRL_BREAK_EVENT:
Beep(700, 200);
printf(“Ctrl-Break event : Starting depoisoning process”);
return(FALSE);
case CTRL_LOGOFF_EVENT:
Beep(800, 200);
printf(“Ctrl-Logoff event : Starting depoisoning process”);
return(FALSE);
case CTRL_SHUTDOWN_EVENT:
Beep(900, 200);
printf(“Ctrl-Shutdown event : Starting depoisoning process”);
return(FALSE);
default:
Beep(1000, 200);
printf(“Unknown event \”%d\” : Starting depoisoning process”, pControlType);
return(FALSE);
}
