示例1: worker_func
void Console::worker_func () noexcept {
// STDIN
HANDLE in;
// Screen buffer
Nullable<ConsoleScreenBuffer> buffer;
// Console mode when this thread
// started
DWORD mode;
try {
// Get handles
in=get_std_handle(STD_INPUT_HANDLE);
if (!(
// Attempt to cache old console
// mode so that it can be restored
// when this thread exits
GetConsoleMode(
in,
&mode
) &&
// Attempt to set new console mode,
// enabling the receipt of resize
// messages
SetConsoleMode(
in,
mode|ENABLE_WINDOW_INPUT
