Should I increase the driver stack size?

NTDEV

Hi,

I am currently writing a driver that is just giving a usermode client controlled access to the LPT ports on a system. Once I have retrieved the device object pointer for the \Device\ParallelPortX that I am going to control, do I need to increase the driver stack size? My feeling says no, because I am not filtering the other device, but I have seen an example where this is done %-)

Cheers,

Oliver

If you are not attaching, you don't need to touch the StackSize

Note that most client’s print jobs end in a spooler, so, the spooler is
nearly the only user of \Device\ParallelPortX.
