Dear ce gurus,

does anybody know what happens when
one application called DeviceIoControl(IOCTL_xxx)
to the driver and is waiting while driver
will process IOCTL_xxx and DeviceIoControl will
return back. And in the same time another application
makes the same DeviceIoControl(IOCTL_xxx) to
the same driver.

What happens in this situation? Will IOCTL_xxx
request from the second app be delayed until IOCTL_xxx
from the first app will be processed?

Thanks
