没有什么好解释的，直接看代码吧

#include <iostream>
#include <sstream>
using namespace std;
BOOL ConsoleEventHandler(DWORD dwCtrlType)
{
    switch(dwCtrlType)
    {
    case CTRL_C_EVENT:// handle the ctrl-c signal
        {
            printf( "ctrl-c event\n\n" );
            return TRUE;
        }
    case CTRL_CLOSE_EVENT:// ctrl-close: confirm that the user wants to exit.
        {
            printf( "ctrl-close event\n\n" );
            return TRUE;
        }
    case CTRL_BREAK_EVENT:// pass other signals to the next handler.
        {
            printf( "ctrl-break event\n\n" );
            return TRUE;
        }
    case CTRL_LOGOFF_EVENT:
        {
            printf( "ctrl-logoff event\n\n" );
            return FALSE;
        }
    case CTRL_SHUTDOWN_EVENT:
        {
            printf( "ctrl-shutdown event\n\n" );
            return FALSE;
        }
    default:
        {
            return FALSE;
        }
    }
}
void main()
{
    if(SetConsoleCtrlHandler((PHANDLER_ROUTINE)ConsoleEventHandler, true ))
    {
        printf( "\nthe control handler is installed.\n" );
        printf( "\n -- now try pressing ctrl+c or ctrl+break, or" );
        printf( "\n try logging off or closing the console...\n" );
        printf( "\n(...waiting in a loop for events...)\n\n" );
        while(TRUE)
        {
            //Do not let me go baby
            Sleep(5000);
        }
    }
    else
    {
        printf( "\nerror: could not set control handler");
    }
}
