Hey, entries in /proc are generally just callbacks to "read" functions you implement. There is nothing like value in /proc getting refreshed after particular time. Each time you open the /proc file your callback function gets called and that function puts the contents in the /proc/<filename> buffer. So each time u call read on /proc file what ever your callback returns gets showed as contents of file. If u want to file gets refreshed only after 2 mins, implement this functionality in the callback itself. i.e. 1. store the value u get at time x in a buf 2. whenever function gets called if diff between current time and time at which I stored the value is more that 2 mins 3. If YES then call the actual callback routen ELSE just dump the old values stored in the buffer.
