Re: Limitations Within a Driver

Oh, I was just looking for another way of configuring my device driver from user space. The sysctl mechanism was suggested by a gentlemen a few days ago. But I don't believe it will work in my situation. This device is one of a series. Several devices of the same model can be connected on a single system. And there is no way of identifying each device uniquely, other than USB address. So I would need a set of settings for every (model, USB address). I don't see sysctl being applicable here. Tell me if I'm wrong. I just thought it might be easier to have the configuration done via a pipe or message queue. Any suggestions?
Regards,
Justin

Can named pipes, sockets and signals be used from within a driver,
specifically an I/O Kit kernel audio driver? I have been told that disk
I/O cannot be performed from within a driver? Is this true? If so,
does
this exclude the use of a disk based IPC such as a named pipe?
Thanks,
