SendInput INPUT struct missing?

[toqueteos]

Hi there Alexander,

I'm trying to simulate keystrokes but unfortunately win lacks the INPUT struct required. Is there any "easy" way to port it from the C headers to Go?

There's this other package which uses cgo to deal with it but in the project I'm working on I can't use cgo :-1:...

Thanks!

Here's what I translated:

// type INPUT struct {
//   DWORD type;
//   _ANONYMOUS_UNION union {
//      MOUSEINPUT mi;
//      KEYBDINPUT ki;
//      HARDWAREINPUT hi;
//   } DUMMYUNIONNAME;
// } INPUT,*PINPUT,*LPINPUT;

type INPUT struct {
    Type      uint32
    AnonUnion interface{}
}

// typedef struct tagMOUSEINPUT {
//   LONG      dx;
//   LONG      dy;
//   DWORD     mouseData;
//   DWORD     dwFlags;
//   DWORD     time;
//   ULONG_PTR dwExtraInfo;
// } MOUSEINPUT, *PMOUSEINPUT;

type MOUSEINPUT struct {
    Dx          int32
    Dy          int32
    MouseData   uint32
    DwFlags     uint32
    Time        uint32
    DwExtraInfo uintptr // int?
}

// typedef struct tagKEYBDINPUT {
//   WORD      wVk;
//   WORD      wScan;
//   DWORD     dwFlags;
//   DWORD     time;
//   ULONG_PTR dwExtraInfo;
// } KEYBDINPUT, *PKEYBDINPUT;

type KEYBDINPUT struct {
    WVk         int16
    WScan       int16
    DwFlags     uint32
    Time        uint32
    DwExtraInfo uintptr // int?
}

// typedef struct tagHARDWAREINPUT {
//   DWORD uMsg;
//   WORD  wParamL;
//   WORD  wParamH;
// } HARDWAREINPUT, *PHARDWAREINPUT;

type HARDWAREINPUT struct {
    UMsg    uint32
    WParamL int16
    WParamH int16
}

It's already there: https://github.com/lxn/win/blob/master/user32.go#L1376
