I agree, but I don't think mentioning such an exception is a good idea. That's basically the same reason why gets() is part of ISO C90 and C99. Just call snprintf() even in such cases and forget about sprintf().

From http://www.open-std.org/jtc1/sc22/wg14/www/C99RationaleV5.10..., PDF page 163:

>The Committee decided that gets was useful and convenient in those special circumstances when the programmer does have adequate control over the input, and as longstanding existing practice, it needed a standard specification.

Fair enough... it's not like snprintf has any noticeable overhead. Sometimes I use sprintf just to indicate to readers of the code that the output is not expected to be truncated, but that's probably too cowboy for my own good.

For the record, when writing new code, I'd strongly recommend that people consider using asprintf instead of either function.
