RE: device driver

["V.Kugan" <kugan@xxxxxxxxxxxxx>]

Hi Amit
Thank you very much, but still I have few more doubts.
Yes , as u say i will heve to implement functions in file_operation
structure and register that with the kerlnal while initializing the device
driver.
But my question is about tty_driver struct and tyy driver and how to use and
what is the difference between this and the earlier, May be I am missing the
whole point here :(  .
Thank you very much
V.Kugan

Read this article by Alan Cox on network buffers and memory management.
It talks of some basics of device drivers.

http://www2.linuxjournal.com/lj-issues/issue30/1312.html

In general u might want to implement atleast the ioctl, open and close
operations in the file_structure.

A good place to start loooking at sample code is drivers/net/skeleton.c

ciao,
Amit
ps. and yes as someone pointed out, Rubini's book is good for basics
