IDirectInputDevice2::GetForceFeedbackState

The IDirectInputDevice2::GetForceFeedbackState method retrieves the state of the device's force feedback system.

HRESULT GetForceFeedbackState(
  LPDWORD pdwOut  
);
 

Parameters

pdwOut
Location for flags that describe the current state of the device's force feedback system.

The value is a combination of the following constants:
DIGFFS_ACTUATORSOFF
The device's force feedback actuators are disabled.
DIGFFS_ACTUATORSON
The device's force feedback actuators are enabled.
DIGFFS_DEVICELOST
The device suffered an unexpected failure and is in an indeterminate state. It must be reset either by unacquiring and reacquiring the device, or by sending a DISFFC_RESET command.
DIGFFS_EMPTY
The device has no downloaded effects.
DIGFFS_PAUSED
Playback of all active effects has been paused.
DIGFFS_POWEROFF
The force feedback system is not currently available. If the device cannot report the power state, then neither DIGFFS_POWERON nor DIGFFS_POWEROFF will be returned.
DIGFFS_POWERON
Power to the force feedback system is currently available. If the device cannot report the power state, then neither DIGFFS_POWERON nor DIGFFS_POWEROFF will be returned.
DIGFFS_SAFETYSWITCHOFF
The safety switch is currently off, meaning that the device cannot operate. If the device cannot report the state of the safety switch, then neither DIGFFS_SAFETYSWITCHON nor DIGFFS_SAFETYSWITCHOFF will be returned.
DIGFFS_SAFETYSWITCHON
The safety switch is currently on, meaning that the device can operate. If the device cannot report the state of the safety switch, then neither DIGFFS_SAFETYSWITCHON nor DIGFFS_SAFETYSWITCHOFF will be returned.
DIGFFS_STOPPED
No effects are playing and the device is not paused.
DIGFFS_USERFFSWITCHOFF
The user force feedback switch is currently off, meaning that the device cannot operate. If the device cannot report the state of the user force feedback switch, then neither DIGFFS_USERFFSWITCHON nor DIGFFS_USERFFSWITCHOFF will be returned.
DIGFFS_USERFFSWITCHON
The user force feedback switch is currently on, meaning that the device can operate. If the device cannot report the state of the user force feedback switch, then neither DIGFFS_USERFFSWITCHON nor DIGFFS_USERFFSWITCHOFF will be returned.

Future versions of DirectInput may define additional flags. Applications should ignore any flags that are not currently defined.

Return Values

If the method succeeds, the return value is DI_OK.

If the method fails, the return value may be one of the following error values:

DIERR_INPUTLOST
DIERR_INVALIDPARAM
DIERR_NOTEXCLUSIVEACQUIRED
DIERR_NOTINITIALIZED
DIERR_UNSUPPORTED

Remarks

The device must be acquired at the exclusive cooperative level for this method to succeed.
