read/write functions working
-
I want to know how a read/write calls is accomplished in linux? I mean how a function say read() will read the data from a file. What all will be the steps from user mode read() function call to kernel mode? Will anybody explain the steps or let me know any site from where I can get this info?

It's not possible to give a complete answer to this question here. I would suggest you find a copy of the Linux source (it's open source so free) and read through the code. Alternatively I expect there are many books describing how Linux works, try a Google search for some possibilities.
It's time for a new signature.
