Hmmm… this should work, ndis.h defines the NdisMSendComplete() macro and it uses that member… strange… What do you think? I could also hook a SendCompleteHandler inside NDIS_OPEN_BLOCK, but, that would not be the earliest function… What do you think?
If miniport driver was compiled with BINARY_COMPATIBLE flag set (allows having same binary for Windows 9x and NT) then NdisMSendComplete called as NDIS export not as macro. May be this is the reason…
