Hi.

I'd like to know what is the purpose of the last (4th)
argument of the proc file system operating functions like
read and write ? The type of the argument is "loff_t *".

When, how and why that (? offset ?) argument should be used 
and when it can be ignored ?
( i.e. what is the meaning of the argument )

Other things/arguments were obvious or I figured them out
by "using the source" but I just didn't find out the correct
way to use that argument...

Thank U.
