IOCTL_INTERNAL_MOUSE_CONNECT control code

The IOCTL_INTERNAL_MOUSE_CONNECT request connects the Mouclass service to a mouse device.

After I8042prt receives a mouse connect request, it sends a synchronous IOCTL_INTERNAL_I8042_HOOK_MOUSE request to the top of mouse device stack. The connect request is completed after the IOCTL_INTERNAL_I8042_HOOK_MOUSE request is completed.

Input Parameters

Parameters.DeviceIoControl.Type3InputBuffer points to a CONNECT_DATA (Mouclass) structure. This structure includes a pointer to a device object and a pointer to a mouse class service callback routine. The connect data is set by the class service and can be filtered (reset) by filter drivers.

Parameters.DeviceIoControl.InputBufferLength specifies the size, in bytes, of a CONNECT_DATA structure.
