The VJOYD_OpenConfigKey_Service macro is used by joystick drivers to open a configuration key. This should mirror the IDirectInputJoyConfig8::OpenConfigKey method.

VJOYD_OpenConfigKey_Service, SERVICE
  • ENTRY:
    eax = ID of key to open

    ecx = address of a DWORD in which to store the key

  • EXIT:
    eax = same as _RegOpenKey except that ERROR_CANTOPEN is returned if VJoyD has not yet established the current configuration key.
