MOUSE_UNIT_ID_PARAMETER structure (ntddmou.h)
MOUSE_UNIT_ID_PARAMETER specifies a unit ID that Mouclass assigns to a mouse.
Syntax
typedef struct _MOUSE_UNIT_ID_PARAMETER {
USHORT UnitId;
} MOUSE_UNIT_ID_PARAMETER, *PMOUSE_UNIT_ID_PARAMETER;
Members
UnitId
Specifies the unit number of the mouse device. A mouse device name has the format \Device\PointerPortN, where the suffix N is the unit number of the device. For example, a device, whose name is \Device\PointerPort0, has a unit number of zero, and a device, whose name is \Device\PointerPort1, has a unit number of one.
Remarks
Although this structure is used with an IOCTL_MOUSE_QUERY_ATTRIBUTES request, Mouclass does not use the UnitId value.
