FwpsAllocateCloneNetBufferList0 returns C022001C

Hi All

I am trying to develop a sample callout driver . I am working On
Ale_Auth_Recv_Accept Layer… my Code Part For Creating Clone is

NET_BUFFER_LIST* netBufferList = (NET_BUFFER_LIST*)packet;
NET_BUFFER_LIST* clonedNetBufferList = NULL;

status =
FwpsAllocateCloneNetBufferList0(netBufferList,NULL,NULL,0,&clonedNetBufferList);

if (!NT_SUCCESS(status))

{

classifyOut->actionType = FWP_ACTION_BLOCK;

classifyOut->rights &= ~FWPS_RIGHT_ACTION_WRITE;

log((LOG_INFO,“FwpsAllocateCloneNetBufferList0 return :%X”,status));

goto cleanup;

}

before calling this function i use to check the layer data
pointer too… But in All the case i got the Error C022001C …I don`t Think I
am Passing Any Invalid Pointer Here…Please help me to find the problem…
is it my code problem?

Thanks

At this layer “packet” is not a NetBufferList. You’re at a “stream-layer”…If “packet” parameter is != NULL try to cast to FWPS_STREAM_CALLOUT_IO_PACKET0.

Thanks Frank…it works now… actually i was doing a silly mistake that i
was executing this to VISTA 5384 build so it was generating such error…

one thing … what adjectly we get at ale layers … My major
work is to make a clone of original packet which invoked at ale…pending
this and again reinjecting back…
