IDirectInputDevice8::WriteEffectToFile Method

Saves information about one or more force-feedback effects to a file that can be read by using IDirectInputDevice8::EnumEffectsInFile. This method is chiefly of interest to those wanting to write their own force-authoring applications.

Syntax

HRESULT WriteEffectToFile(      

    LPCSTR lpszFileName,
    DWORD dwEntries,
    LPCDIFILEEFFECT rgDiFileEft,
    DWORD dwFlags
);

Parameters

lpszFileName

Name of the RIFF file.

dwEntries

Number of structures in the rgDiFileEft array.

rgDiFileEft

Array of DIFILEEFFECT structures.

dwFlags

Flags which control how the effect should be written. This can be DIFEF_DEFAULT (= 0) or the following value:

DIFEF_INCLUDENONSTANDARD

Includes effects that are not defined by Microsoft?DirectInput? If this flag is not specified, only effects with globally unique identifiers (GUIDs) defined in Dinput.h, such as GUID_ConstantForce, are written.

Return Value

If the method succeeds, it returns DI_OK.

If it fails, the return value can be DIERR_INVALIDPARAM.
