StatusFromWin()

Status StatusFromWin

(

)

Returns

the Status equivalent of GetLastError(), or ERR::FAIL if there's no equivalent. SetLastError(0) should be called before the Windows function to make sure no stale errors are returned.

WINIT_REGISTER_EARLY_INIT()

(

wutil_Init

)

WINIT_REGISTER_LATE_SHUTDOWN()

wutil_Allocate()

void* wutil_Allocate

(

size_t

size

)

wutil_AppWindow()

HWND wutil_AppWindow

(

)

Returns

handle to the first window owned by the current process, or 0 if none exist (e.g. it hasn't yet created one).

enumerates all top-level windows and stops if PID matches. once this function returns a non-NULL handle, it will always return that cached value.
