DirectInputCreate (Windows CE 5.0)
This function is not supported as of Windows CE .NET 4.2 and Windows Mobile 2003. This function creates a DirectInput object that supports the IDirectInput COM interface.
HRESULT WINAPI DirectInputCreate(HINSTANCE hinst,DWORD dwVersion,LPDIRECTINPUT* lplpDirectInput,LPUNKNOWN punkOuter);
Parameters
hinst
Instance handle to the application or dynamic-link library (DLL) that is creating the DirectInput object. DirectInput uses this value to determine whether the application or DLL has been certified and to establish any special behaviors that may be necessary for backward compatibility.It is an error for a DLL to pass the handle to the parent application. For example, an ActiveX control embedded in a Web page that uses DirectInput must pass its own instance handle, and not the handle to the Web browser. This ensures that DirectInput recognizes the control and can enable any special behaviors that might be necessary.
dwVersion
Version number of DirectInput for which the application is designed. This value is normally DIRECTINPUT_VERSION. Passing the version number of a previous version causes DirectInput to emulate that version. For more information, see Designing for Previous Versions of DirectInput.lplpDirectInput
Address of a variable to receive a valid IDirectInput interface pointer if the call succeeds.punkOuter
Pointer to the address of the controlling object's IUnknown interface for COM aggregation, or NULL if the interface is not aggregated. Most callers pass NULL. If aggregation is requested, the object returned in *lplpDirectInput is a pointer to the IUnknown, rather than an IDirectInput interface, as required by COM aggregation.
Return Values
If the function succeeds, the return value is DI_OK. If the function fails, the return value can be one of the following error values.
| Value | Description |
|---|---|
| DIERR_BETADIRECTINPUTVERSION | The application was written for an unsupported prerelease version of DirectInput. |
| DIERR_INVALIDPARAM | An invalid parameter was passed to the returning function, or the object was not in a state that permitted the function to be called. This value is equal to the E_INVALIDARG standard COM return value. |
| DIERR_OLDDIRECTINPUTVERSION | The application requires a newer version of DirectInput. |
| DIERR_OUTOFMEMORY | The DirectInput subsystem could not allocate sufficient memory to complete the call. This value is equal to the E_OUTOFMEMORY standard COM return value. |
Remarks
Only the Unicode version of this function is supported.
Calling the function with punkOuter = NULL is equivalent to creating the object through CoCreateInstance (&CLSID_DirectInput, punkOuter, CLSCTX_INPROC_SERVER, &IID_IDirectInput, lplpDirectInput), then initializing it with Initialize.
Calling the function with punkOuter != NULL is equivalent to creating the object through CoCreateInstance(&CLSID_DirectInput, punkOuter, CLSCTX_INPROC_SERVER, &IID_IUnknown, lplpDirectInput). The aggregated object must be initialized manually.
To determine whether the platform supports this function, see Determining Supported COM APIs.
