Mac MSG_PostAltF4Keys: void __cdecl (void)

checked · by KierTaylor · submitted 2026-11-08

It reads no register or stack args. It posts the synthetic Alt+F4 sequence through MSG_EnqueueMessage 0x000297df (regparm: ECX=msg, EDX=wParam, [ESP]=lParam 0): WM_KEYDOWN VK_MENU|0x80000000, WM_KEYDOWN VK_F4, WM_KEYUP VK_F4, WM_KEYUP VK_MENU. Plain RET; EAX is only the last enqueue result. The caller MAC_HandleMenuCommand 0x0019bcc2 JMPs on without reading EAX.
