I would say that this is impossible in principle. On some systems, other 
concurrent programs can write more data into the input file as your 
program is reading the file, so the input file can grow during the 
execution of the program, and may not even have any fixed upper bound on 
its size (apart from the total space available in the system).

IMO the only robust way is to read all of standard input and store it 
within the program, or in a temporary file, and then process the stored 
data.
