-description

The IOCTL_LAMP_SET_INTENSITY_COLOR control code sets the lamp to the specified light intensity.

#define IOCTL_LAMP_SET_INTENSITY_COLOR \
    CTL_CODE(IOCTL_LAMP_BASE, 0x0007, METHOD_BUFFERED, FILE_ANY_ACCESS)

-ioctlparameters

-ioctl-major-code

-input-buffer

Irp->AssociatedIrp.SystemBuffer points to a LAMP_INTENSITY_COLOR structure.

-input-buffer-length

Length of a LAMP_INTENSITY_COLOR structure.

-output-buffer

None.

-output-buffer-length

None.

-in-out-buffer

-inout-buffer-length

-status-block

The driver sets Irp->IoStatus.Status to STATUS_SUCCESS or the appropriate error status.

If the device has been acquired by a camera driver, the lamp driver should return a STATUS_RESOURCE_IN_USE error via Irp->IoStatus.Status.
