Mac IDirectSound_SetCooperativeLevel: int32_t __cdecl (pDirectSound, pWindow, dwLevel) shim

checked · by KierTaylor · submitted 2026-11-08

This is the Mac DirectSound shim. The body ignores its args and returns XOR EAX,EAX (S_OK). The caller SOUND_InitDirectSound 0x002e72b6 stores three args, [ESP]=the DirectSound object (EDI), [ESP+4]=the window from 0x002b5b6d and [ESP+8]=2 (DSSCL_PRIORITY), then tests the HRESULT (TEST EAX,EAX / JS). This is the flattened form of IDirectSound::SetCooperativeLevel(this, HWND, DWORD).
