Initialize callback function

  • Article

In DirectX 5.0 and later, the Initialize callback signals the driver about the identity of the device. This callback replaces the joystick identification callback (see Joystick Identification Callback) used in previous versions of DirectX.

Syntax

HRESULT Initialize(
   DWORD            dwDeviceID,
   LPDID_INITPARAMS lpInitParams
);

Parameters

  • dwDeviceID
    Indicates the joystick ID number being used. The Windows joystick subsystem allocates external IDs.

  • lpInitParams
    Points to a DID_INITPARAMS structure that contains the initialization parameters.

Return value

When access is being started, returns S_OK on success; otherwise returns an error value if the driver cannot service this ID. The result is ignored if access is being stopped.
