[plug] kernel programming

[Peter F Bradshaw]

Hi Parag;

If you are talking about the fopen() function call then you are talking
about libc - and libc is not avaliable in the kernel. In fact only those
functions defined in the kernel (or a module) are avaliable.

Kernel programming and user mode programming are quite different - the
enviroment and the implicit assumptions are different. Its hard to know
why you would need to use fopen() in the kernel but if you really do
then you may want to address what ever you are trying to do by writing a
kernel and corresponding user mode components and doing the nasty stuff
in user mode. There are a few ways to communicate - probably using the
/proc file system is easiest (might be messy though :-).

You did not say which kernel version you are talking about but for 2.4
take a look at:
