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");
        }
    }
