D3DKMT_GETDEVICESTATE structure

The D3DKMT_GETDEVICESTATE structure describes parameters for retrieving the state of a device.

Syntax

typedef struct _D3DKMT_GETDEVICESTATE {
  D3DKMT_HANDLE           hDevice;
  D3DKMT_DEVICESTATE_TYPE StateType;
  union {
    D3DKMT_DEVICEEXECUTION_STATE     ExecutionState;
    D3DKMT_DEVICEPRESENT_STATE       PresentState;
    D3DKMT_DEVICERESET_STATE         ResetState;
    D3DKMT_DEVICEPRESENT_STATE_DWM   PresentStateDWM;
    D3DKMT_DEVICEPAGEFAULT_STATE     PageFaultState;
    D3DKMT_DEVICEPRESENT_QUEUE_STATE PresentQueueState;
  };
} D3DKMT_GETDEVICESTATE;

Members

hDevice

[in] A handle to the device that status is requested for.

StateType

[in] A D3DKMT_DEVICESTATE_TYPE-typed value that indicates the type of status to retrieve for the device.

ExecutionState

[out] A D3DKMT_DEVICEEXECUTION_STATE-typed value that indicates the execution status of the device. The union that is contained in D3DKMT_GETDEVICESTATE holds a value from this enumeration if the StateType member is D3DKMT_DEVICESTATE_EXECUTION.

PresentState

[in/out] A D3DKMT_DEVICEPRESENT_STATE structure that describes parameters for retrieving the present status of the device. The union that is contained in D3DKMT_GETDEVICESTATE holds a structure of this type if the StateType member is D3DKMT_DEVICESTATE_PRESENT.

ResetState

[out] A D3DKMT_DEVICERESET_STATE structure that describes the reset status of the device. The union that is contained in D3DKMT_GETDEVICESTATE holds a structure of this type if the StateType member is D3DKMT_DEVICESTATE_RESET.
