Registers input ring.
#include <sys/inputdd.h>
 int ioctl (FileDescriptor, LPFKREGRING, Arg)
int FileDescriptor;
struct uregring *Arg;
The LPFKREGRING ioctl subroutine call specifies the address of the input ring and the value to be used as the source identifier when enqueuing reports on the ring. A subsequent LPFKREGRING ioctl subroutine call replaces the input ring supplied earlier. Specify a null input ring pointer to disable LPFK input.
