What happens internally when we create a file in Linux

Hi All,

I am using NetBSD-5.1.
1. I wanted to know what happens internally when we create a file in linux. ?

The header file STDIO.H present in "src/include/stdio.h" contains a "FILE" structure with various members like _p, _cookie, etc.

2. I wanted to know how does internally memory gets allocated for them.?

Thanks,

So I recommend you to read man page for fopen, and if that's not enough go to the source of fopen and study it.
