C++捕捉关闭控制台应用程序事件

#include <windows.h> #include <stdio.h> bool ctrlhandler( DWORD fdwctrltype ) {     switch( fdwctrltype )     {     // handle the ctrl-c signal.     case CTRL_C_EVENT:         printf( "ctrl-c event\n\n" );        return( true );    // ctrl-close: confirm that the user wants to exit.     case CTRL_CLOSE_EVENT:         printf( "ctrl-close event\n\n" );        return( true );     // pass other signals to the next handler.     case CTRL_BREAK_EVENT:         printf( "ctrl-break event\n\n" );        return false;     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( void ) {     // 控制台添加或删除应用程序处理函数列表;    if( SetConsoleCtrlHandler( (PHANDLER_ROUTINE) ctrlhandler, 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( 1 ){ Sleep(100);}     } else     printf( "\nerror: could not set control handler"); }
