-description

The IOCTL_KEYBOARD_SET_INDICATORS request sets the keyboard indicators.

-ioctlparameters

-input-buffer

AssociatedIrp.SystemBuffer points to a client-allocated buffer that inputs a KEYBOARD_INDICATOR_PARAMETERS structure. The client sets the indicator parameters in this structure.

Parameters.DeviceIoControl.InputBufferLength is set to a value greater than or equal to the size, in bytes, of a KEYBOARD_INDICATOR_PARAMETERS structure.

-input-buffer-length

The size of a KEYBOARD_INDICATOR_PARAMETERS structure.

-output-buffer

None.

-output-buffer-length

None.

-in-out-buffer

-inout-buffer-length

-status-block

The Information member is set to zero.

The Status member is set to one of the following values:

-STATUS_DEVICE_NOT_READY

The keyboard interrupt is not initialized.

-STATUS_INVALID_PARAMETER

Parameters.DeviceIoControl.InputBufferLength is less than the size, in bytes, of a KEYBOARD_INDICATOR_PARAMETERS structure, or the specified indicator parameters are invalid.

-STATUS_IO_TIMEOUT

The request timed out.

-STATUS_SUCCESS

The request completed successfully.
