Hi,
I need to block indefinetly on an Event in my Ndis Driver
I am setting 0 for MsToWait in NdisWaitEvent. But
NdisWaitEvent at times comes out of the wait even if no NdisSetEvent is issued.
Am i missing something ? Any one any clue ?
Regards
Anandhi

Your other question about NdisMSleep() leads me to the assumption you
are calling NdisWaitEvent() from APC_LEVEL? This is an illegal
operation as NdisWaitEvent() can only be called at PASSIVE_LEVEL.
NDIS drivers usually only know of PASSIVE_LEVEL, DISPATCH_LEVEL, and
DIRQL. How come your NDIS driver runs at APC_LEVEL?

I hope in your wait thread, you do something like this :
WAIT THREAD:
while(bThread)
{
NdisWaitEvent(&event, 0);
NdisResetEvent(&event);
.
//do rest of stuff
.
}
Good luck.

Hi,
I am calling NdisWaitEvent() from passive level. The problem was there was
no proper match between NsdsiSetEvent & NdisResetEvent.
My question about NdisMSleep has got nothing to do with Event issue, infact
that’z why i posted them as separate queries :o)
Regarding APC_LEVEL, my driver is NdisMiniport with WDM Lower edge. One of
my lower drivers calls my driver at this Level
regards

Hi Sharma,
My code was like
FunctionABC()
{
…
NdisSetEvent(&event)
…
}
WAIT THREAD:
while(bThread)
{
if(condition A)
{
NdisWaitEvent(&event, 0);
NdisResetEvent(&event);
}
.
//do rest of stuff
.
}
The problem with this code is if condition A is not satisfied a reset will
not be done at all. Thus nuber of sets & resets do not match
The code needs to be changed to
WAIT THREAD:
while(bThread)
{
if(condition A)
{
NdisWaitEvent(&event, 0);
}
NdisResetEvent(&event);
.
//do rest of stuff
.
}
Thanx & Regards
Anandhi
