New driver writer

[Rick Hunnicutt]

Hello all,
 
I'm writing a BSD PCI character driver and have many questions. I have the architecture handbook and it answers some questions but leaves much unaddressed. For example, the parameters on the open/close/read/write calls don't seems to be address. Am I expected to dig around the code base to decipher their purpose or have I missed a vital area of documentation?
 
Thank you for your help.
 
Rick
