- Reply-to: "Yi Tang" <yitang at itee dot uq dot edu dot au>
Hello,
It's the first time for me to write a device driver. I have got a simple,
silly question, hope someone in this group can instruct me.
In the eCos reference, I found that there is one item in nearly all io
functions, the "C label".
like this one:
DEVTAB_ENTRY(l, name, dep_name, handlers, init, lookup, priv)
l: The "C" label for this entry.
also can be found in DEVIO_TABLE and other functions.
Can anyone tell me what it is used for and which element I should assign it
to?
Regards,
Tony
