Hi All,
   
    Can any one tell me sources to refer to write elegant C coding/ best 
practices in C coding.

Check the kernel sources under Documentation/CodingStyle

What I mean is both elegant and _efficient_ best practices in C coding.

Documentation/CodingStyle is well worth a read. Also for that matter
just reading a lot of good code helps you write good code as reading
helps you learn a language better.

Efficiency is a harder subject: Remember that efficient code still must
be easy to understand so often is about algorithms not language, and in
part about hardware.

On the hardware side - the book "Unix systems for modern architectures"

But as Tim righly said "practice"

Look for "Writing Efficient Programs", by Jon Bentley (sadly out of print),
and his "Programming Pearls" (2nd edition).

Keep in mind that "efficient" is mostly a thing of overall organization and
careful design (and data structure definition), not detailed programming.
Microoptimizations are usually counter-productive, at least by making the
code unnecessarily hard to read; current compilers aim at generating code
from "normally written C" that is at least as good as that a competent
assembly programmer would write with care (and often writing "more
efficient source code" just confuses the compiler into giving worse
results). Better aim at understandable, easy to get right code. If you
_measure_ later that it is too slow/large/..., _then_ go back and see how
to make it better. So Documentation/CodingStyle is an excellent starting
point.

Thank you very much.

I'd say better to study compile theory and a kind of compiler source code.

Yes, gcc source definitely makes a great cautionary tale about the need of
writing elegant code and dreadful results of not doing so.

Hi,

Thank you very much for refering me for "programming pearls".
