I8042prt Callback Routines

This section describes the callback routines that I8042prt supports:

I8042prt uses IOCTL_INTERNAL_I8042_HOOK_KEYBOARD and IOCTL_INTERNAL_I8042_HOOK_KEYBOARD requests to add, or hook, the filter driver callbacks into the operation of I8042prt. A hook request also passes pointers to the I8042prt keyboard callbacks to the filter driver.
