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_Shutdown

)

void* wutil_Allocate

(

size_t

size

)

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.

HMODULE wutil_LibModuleHandle

(

)

Returns

module handle of lib code (that of the main EXE if linked statically, otherwise the DLL). this is necessary for the error dialog.
