We are writing an spi driver. How can I set the "chip select pin" for linux ds3234 driver? Name of the functions of the header file that can help would be appreciated.

I'm new to C++ and I'm having some trouble trying to compile my program. I have a Driver.cpp file which contains main(), and 2 header files each with corresponding .cpp files. They are all in the same directory. The Driver.cpp file only calls a function in one of the other header files, which does the rest of the work.
being a total newbie i have my first install of ubuntu 13.10 on my desktop dual booted with windows 7. All good except for my M-Audio delta 192 sound card not responding. I installed mudita24 (envy24) but i think this is ALSA (dont know what that is) code for ice1712 chip. I now get some sound out but massively distorted, way too much gain.
I am trying to write my first char driver and i am trying to support a select interface for it as well. But I don't see any select option in fops. I found some links indicating that select() needs to be implemented through poll() and all. Tried some experiments and none seems to be yielding any postive feedback.
I'm close to giving up my plans of installing 12.04, because I can't get my wlan chip to work.
It's a Broadcom b43225, and I've tried lots of things already.
The same chip works under Bodhi Linux 1.4, which is based on Ubuntu (currently 10.04).
I have a PCI-E/104 board self production. I wanna write driver for him. But manuals and book Linux Device Drivers have a structures and functions of lang 'C', what not supproted by kernel 3.10.19 (Slackware 14.1 x64). Where I can search actual manual on writing driver for this kernel version?
i have a Asus x501a rt3970 wireless chip and i installed thier rt2860 driver as the wifi driver using rt2800pci build was not very good bad signal etc. i went though the read me and compiled it etc and now i have it installed (rt2860) and working.
