Sets mouse reporting threshold.
#include <sys/inputdd.h> int ioctlFileDescriptor, MTHRESHOLD, Arg) int FileDescriptor; ulong *Arg;
The MTHRESHOLD ioctl subroutine call sets the minimum horizontal or vertical distance (in counts) that the mouse must be moved before the driver reports an event. The high-order two bytes of the Arg parameter specify the horizontal threshold and the low-order two bytes specify the vertical threshold. The minimum threshold is 0, while the maximum threshold is 32767. The default horizontal and vertical mouse reporting threshold is 22.
