procfs question

[yenganti pradeep <pradeepls143@yahoo.co.in>]

Hi,

I've created a new entry under /proc, to make tests.

I've defined an static int var=0;

Then I link my proc entry read function to a function
that only performs this:

int length;
length=sprintf(page,"Value %d",var++);

return length;

But when I cat/vi the file continuosly I get:

Value 0
Value 3
Value 6

etc...

Why is this three numbers increment? 

Thanks
Pradeep
