IDirectInputDevice8::GetCapabilities Method

  • Article

Obtains the capabilities of the DirectInputDevice object.

Syntax

HRESULT GetCapabilities(
         LPDIDEVCAPS lpDIDevCaps
)

Parameters

  • lpDIDevCaps
    Address of a DIDEVCAPS structure to be filled with the device capabilities. The dwSize member of this structure must be initialized before calling this method.

Return Value

If the method succeeds, the return value is DI_OK. If the method fails, the return value can be one of the following error values: DIERR_INVALIDPARAM, DIERR_NOTINITIALIZED, E_POINTER.

Remarks

For compatibility with DirectX 3, it is also valid to pass a DIDEVCAPS_DX3 structure with the dwSize member initialized to sizeof(DIDEVCAPS_DX3).

The number of objects returned in the DIDEVCAPS structure is the maximum number of objects that could be enumerated. However, all of these objects are not necessarily returned during a call to IDirectInputDevice8::EnumObjects.
