[SDL] SDL_JoystickOpen() error

[Ed Phillips]

Hello,

I'm getting the following when trying to open a joystick that is DINPUT
using SDL 2.0.4 on Windows:

"IDirectInputDevice8::SetCooperativeLevel() DirectX error 0xx"

Any ideas why I'd be getting this kind of failure? SDL is init'd and
XINPUT joysticks seem to be working fine when I get this error, so it must
be something specific to DINPUT.

The error code is botched. It likely has something to do with this code
in SDL_dinputjoystick.c:

/* Convert a DirectInput return code to a text message */
static int
SetDIerror(const char *function, HRESULT code)
{
/*
return SDL_SetError("%s() [%s]: %s", function,
DXGetErrorString9A(code), DXGetErrorDescription9A(code));
*/
return SDL_SetError("%s() DirectX error 0x%8.8lx", function, code);
}

It looks like SDL_SetError() doesn't actually handle the "l", and as I
understand it, HRESULT is 32-bit anyway... so that probably explains why
I'm not seeing the actual error code from DINPUT.

Oddly enough, this problem is not occurring with 2.0.5. However, the code
in the SDL_SetError call (formatting spec "0x%8.8lx") looks to still be
there and needs fixing so the error codes show up correctly.
