Functions

func ReadConsoleInput

func ReadConsoleInput(h windows.Handle, buf []InputRecord) (int, error)

ReadConsoleInput input wraps the homonymous Windows API call.

func WaitForMultipleObjects

func WaitForMultipleObjects(handles []windows.Handle, waitAll bool,
	timeout uint32) (trigger int, abandoned bool, err error)

WaitForMultipleObjects blocks until any of the objects is triggered or timeout.

DWORD WINAPI WaitForMultipleObjects(

_In_       DWORD  nCount,
_In_ const HANDLE *lpHandles,
_In_       BOOL   bWaitAll,
_In_       DWORD  dwMilliseconds

);

Types

type Coord

type Coord struct {
	X int16
	Y int16
}

type FocusEvent

type FocusEvent struct {
	BSetFocus int32
}

type InputEvent

type InputEvent interface {
	// contains filtered or unexported methods
}

InputEvent is either a KeyEvent, MouseEvent, WindowBufferSizeEvent, MenuEvent or FocusEvent.

type InputRecord

type InputRecord struct {
	EventType uint16
	Pad_cgo_0 [2]byte
	Event     [16]byte
}

func (*InputRecord) GetEvent

func (input *InputRecord) GetEvent() InputEvent

GetEvent converts InputRecord to InputEvent.

type KeyEvent

type KeyEvent struct {
	BKeyDown          int32
	WRepeatCount      uint16
	WVirtualKeyCode   uint16
	WVirtualScanCode  uint16
	UChar             [2]byte
	DwControlKeyState uint32
}

type MenuEvent

type MenuEvent struct {
	DwCommandId uint32
}

type MouseEvent

type MouseEvent struct {
	DwMousePosition   Coord
	DwButtonState     uint32
	DwControlKeyState uint32
	DwEventFlags      uint32
}

type WindowBufferSizeEvent

type WindowBufferSizeEvent struct {
	DwSize Coord
}
