Functions

func DefWindowProc

func DefWindowProc(hwnd, msg, wparam, lparam uintptr) uintptr

DefWindowProc calls the default window procedure to provide default processing for any window messages that an application does not process.

func DestroyWindow

func DestroyWindow(hwnd uintptr) error

DestroyWindow destroys the specified window. The function sends WM_DESTROY and WM_NCDESTROY messages to the window to deactivate it and remove the keyboard focus from it.

func SHCreateMemStream

func SHCreateMemStream(data []byte) (uintptr, error)

func Utf16PtrToString

func Utf16PtrToString(p *uint16) string
