I was just programming along very nicely, writing stuff to a file
to help debug the code and reading it back again when I found
that a line something like this:
printf(filenum,"value %d\n",buffer[x])
produced this line in the file:
value inf
or sometimes:
value nan
I suppose they mean "too big" and "too small" respectively.
Just a little suprise. I expected a number since I had specified
an integer (%d), not a string. Maybe its in the documentation
and I didn't see it. I'll turn off the 'without warning' and run it again.

inf = infinity
nan = not a number
Discussion on these values can be found in section 2.2.3 "Arithmetic
Operators"
