WritePort function (KbdFilter driver)???

Hello,

How I must write routine that writes value to the keyboard
port "WritePort" in upper fiter driver, may somebody show
me sample code.

WritePort(IN PVOID Context,
UCHAR Value,
BOOLEAN WaitForACK)
{
//??????????????
}

NTSTATUS
InitializationRoutine(IN PVOID InitializationContext,
IN PVOID SynchFuncContext,
IN PI8042_SYNCH_READ_PORT ReadPort,
IN PI8042_SYNCH_WRITE_PORT WritePort,
OUT PBOOLEAN TurnTranslationOn)
{
//some code
}

Thanks.

I hate to keep saying RTFM, but look in the ddk help index under
"I8042prt Driver Reference" for documentation and samples.

use the function pointer passed to you in the init routine, ie

(*WritePort)(SyncFuncContext, 0xXX, TRUE /*or FALSE depending on your
hardware/*);

this WritePort function pointer should only be used when you are in the
InitializationRoutine, anytime outside of this function you must use the
appropriate IOCTL to tell i8042prt to do the write for you.
