And I bet it was impossible for you to mention this in the last 6 mails
or so. After all, the system call could possibly have been considered
unsafe because of a buffer overflow or something (and that's so
absolutely very likely what GCC tries warning about). So before
accidently giving one pointer too many, better taunt the other to go out
on a limb before showing him wrong.
There is probably something educational hidden in there, but I am likely
too dull to discern it.
Sorry for the rant. I just think that at times we could be more helpful
towards each other.
