Hi,
reading "Programming the microsoft windows driver model", by Walter
Oney, at page 256 in the sidebar titled "Microsoft Queuing Routines", I
found out that IoStartPacket and IoStartNextPacket "implement a queuing
model that's inappropriate for WDM drivers". I tried to find something
that confirmed those assertions in the Windows Driver Kit docs, but it
seems that those functions aren't officially deprecated. Can I use them
or should I use other techniques instead?

Bye
Alex

Queues implemented by these ancient (NT 3.1) functions use the single
OS-wide global spinlock to protect all "put to queue" and "get to queue"
operations.

IoCsqXxx routines are free from this limitation, so are KMDF queues.

IoStartPacket is just plain deprecated.
