Which I recently wrote by writing some other "recent docs" and then
with the understanding developed from them.
If there is some thing like my previous question for a structure in
super IO chips such things I do not see commonly being used.
I looked at a similar code in vlc media player and found that such a
structure was not known to many many experienced kernel level
programmers and
they found it difficult to understand.
I think Robert JUST mentioned something about thread hijacking in the previous mail. Sorry to say this guys - i don't see how the docs can help people understand the rules. Even this thread about guidelines is not being followed according to the guidelines. Recursion???
If some one is asking a question via a typedef in a function pointer
or structure initialization which he never found any where else on
this planet other than the kernel then what wrong is he doing.That
book does not covers such things.See it is very good to give lecture
to any one who asked question to do blah blah but to understand his
problem and give a solution to some thing specific is not an easy
thing.
Recent example was my character device question where the driver was
dropping characters out of it. I could not understand the reason
behind it some one even blocked me from his mails and one guy actually
solved that problem.
When you are learning some thing then asking questions even the
silliest ones is not wrong.
At least some one who is asking is attempting his level best( upon his
understanding) to understand irrespective of the fact that community
does not appreciates that.
I did read K R after getting busted here and I do not see any one else
other than me asking such C questions and to the best of my knowledge
I did not found any thing the people who suggest to read K R
themselves do not read that book but will give suggestion to read.
KR was written for C in very old times to help people beginning with
programming or what ever reason it does not cover often the way Data
structures are initialized in kernel specific areas.Or some other
relevant stuff.My point is rather than giving some one such a lecture
it will be better to just make a doc with relevant structs,typedefs
and such other tricks which are used in kernel many a times which
might not be commonly found on the wiki and give a link to that may be
if such a thing is present some one whose questions appear silly would
before asking read that doc and will get his answers from there.

Most of the free documentation and kernel books are not worth reading.
