As I said to simplify the programmation, that would not be allowed...

you should rather write numberOfOpenCylinders (if "*fOpen*" is allowed) or
nOpenCylinder... etc...

I hope you all understand it would be rather stupid to code something that would
understand if it's not the function fopen, while I haven't code half the main
program! ;)

I guess it depends on a few things, because I have RedHat 6.1 installed and I
tested it very much to make it crash and the only way I found was to play with
my 3dfx acceleration and even then I'm not sure if the computer is crashed or if
it's only the video that is...

When I start a 3dfx program, at the beginning it prints "unprotecting memory",
holds for ~1 second and start...  if I kill the program when it's unprotecting
the video memory, the video freezes...  

And that's the only crash I found...  there are some bugs that can hang the
computer for some time such as when the memory is getting very low... etc... but
nothing serious...

I think that the most secure way of finding a true fopen is (using
regular expressions):

  (^|[^0-9A-Za-z])fopen($|[^0-9A-Za-z])

  I think that there's a shortcut in perl for [^0-9A-Za-z] but I don't
remember which it was.

My information may be pretty old (several years). Of course bugs are
fixed and features improved over the time.

Note: If the "fopen" is inside a string, it will match that too...

  Making it ignore the word "fopen" if it appears inside a string may be
a lot harder.
  It may be too risky to even try, anyways (there may be too many ways for
fooling the filter to think that the fopen is inside a string when it actually
isn't).

  Right. The regular expression gets much simpler with that:

  (^|\W)fopen($|\W)

  Well, if we are using perl, we can simplify that even more:

  \bfopen\b

I guess so...  my computer is running at 100% of CPU power since a few weeks
24/24 7/7...  And never crashed, I even used to overclock the cpu at some early
times... but I fried my 3dfx... <grin>  so got another 3dfx and stopped
overclocking...  (Celeron 433 could got up to 546mhz!!)  Actually that is not
absolutely true, I rebooted when my 30-days-of-render animation finished... to
prevent any inconvenient...  and as soon as it was ready I started another
animation... that one took only 4 days...

;)
