RE: device driver

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

HI Amit
I am now going through the source of Bluetooth device driver
(www.developer.axis.com) this is implemented as char diver.
In Rubin's Device driver book he is using file_operation structure defining
the function the and registering this structure with the kernal using
register_chr_driver(..).

But in this Bluetooth driver they are using tty_driver and tty_ldisk  and
resgistering with the kernal using tty_register_driver(..)

My question is when we have to use the above and when the lower one. And
also where can I get more details about the second implementation.
If you have any good links any other maerials pls send to me. My e-amil is
kugan@xxxxxxxxxxxxx or
kugan_v@xxxxxxxxx
Thank you verymuch
V.Kugan

I am not sure i understand what your question is ? What about the
tty_driver struct ? Can u be a little more specific ?
