Right, I saw this later, at the end of your patch, but was too lazy to
change my whole message ;-)

Wel, the sprintf() already returns the number of output characters,
i. e. 7.
pkt then points at the terminating '\0' character. strlen() should
always return 0, then. This makes not much sense to me.
Also, why do you need sprintf() at all when the string is a constant
anyway?
Why not simply:
memcpy (pkt, "tsize\00", 7);
pkt += 7;

I know what you mean. OTOH, I tend to dislike such characters
sequences (with lots of backspace characters) because they always
mess up log files ;-)

Thanks.

Right. Thanks a lot.
