Summary
Retrieves the current state of a pointer device.
Prototype
typedef
EFI_STATUS
(EFIAPI *EFI_SIMPLE_POINTER_GET_STATE)
IN EFI_SIMPLE_POINTER_PROTOCOL *This,
IN OUT EFI_SIMPLE_POINTER_STATE *State
);
Parameters
This A pointer to the EFI_SIMPLE_POINTER_PROTOCOL
instance. Type EFI_SIMPLE_POINTER_PROTOCOL is
defined in Section 10.10.
State A pointer to the state information on the pointer device. Type
EFI_SIMPLE_POINTER_STATE is defined in “Related
Definitions” below.

RelativeMovementX The signed distance in counts that the pointer device has been
moved along the x-axis. The actual distance moved is
RelativeMovementX / ResolutionX millimeters. If the
ResolutionX field of the EFI_SIMPLE_POINTER_MODE
structure is 0, then this pointer device does not support an x-axis,
and this field must be ignored.
