* DIDFT_PSHBUTTON,

* DIDFT_MAKEINSTANCE(n).
|
|
*
|
|
* Other bits are reserved and should be ignored.
|
|
*
|
|
* For example, the value 0x0200104 corresponds to

* dwFlags
|

|
|
*
|
|
* This information is passed to drivers to allow for

* is being modified, a driver may be able to update
|
|
* the effect in situ and transmit to the device
|
|
* only the information that has changed.
|
|
*
|
|
* Drivers are not, however, required to implement this

* the effect at each download.

|
*
|
|
* Returns:

|

|
|
* S_OK on success.
|
|
*
|
|
* DI_TRUNCATED if the parameters of the effect were
|
|
* successfully downloaded, but some of them were
|
|
* beyond the capabilities of the device and were truncated.
|
|
*
|
|
* DI_EFFECTRESTARTED if the parameters of the effect
|

* were successfully downloaded, but in order to change
|
|
* the parameters, the effect needed to be restarted.
|
|
*
|
|
* DI_TRUNCATEDANDRESTARTED if both DI_TRUNCATED and
|
|
* DI_EFFECTRESTARTED apply.
|
|
*
|
|
* Any other DIERR_* error code may be returned.
|

*
|
