IDirectInputEffect::Escape Method

  • Article

Sends a hardware-specific command to the driver.

Syntax

HRESULT Escape(
         LPDIEFFESCAPE pesc
)

Parameters

  • pesc
    DIEFFESCAPE structure that describes the command to be sent. On success, the cbOutBuffer member contains the number of bytes of the output buffer used.

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_NOTINITIALIZED, DIERR_DEVICEFULL.

Remarks

Other device-specific error codes are also possible. Ask the hardware manufacturer for details.

Because each driver implements different escapes, it is the application's responsibility to ensure that it is sending the escape to the correct driver by comparing the value of the guidFFDriver member of the DIDEVICEINSTANCE structure against the value the application is expecting.
