If a file is being randomly updated even while you're reading it, then 
the data you're reading in is going to be out of date.

If it's simply being extended as it's being read, then it might grow at 
a faster rate than you can read it!

This makes is harder to do something as simple as reading the data from 
a file into a memory block. Sometimes you have to set aside your 
paranoia and assume the file you're reading is well-behaved. An easy way 
is to make this a requirement of your application.

Otherwise, how does a program even do this:

   gcc file.c

when file.c is still in the middle of being edited (by an editor working 
off disk or performing continuous updates), or is likely to be replaced 
by an entirely different file halfway through being read?

Whatever assumptions a program such as gcc makes about its input files, 
or restrictions it might impose, can be done by any application.
