Hello programmers !
in passthru sample in WDK i found following codes in protocol.c in line of 1241

//
// Set Packet Flags
//
NdisGetPacketFlags(MyPacket) = NdisGetPacketFlags(Packet);

i see that two side of equivalence use same function !!
can u explain me the reason ?

NdisGetPacketFlags is a macro:

#define NdisGetPacketFlags(_Packet) ((_Packet)->Private.Flags)

So your statement reduces to:

MyPacket->Private.Flags = Packet->Private.Flags;

VOID
NdisSetPacketFlags(

);
