:I don't agree with that, since the other functions return the number of
:characters printed as well.
Yes, but not portably. The ANSI standard tried to standardize it but
the reality is that only snprintf()'s return value is portable. If you
try to use the return value from other functions as a count, your code
won't be portable. asprintf() *might* be portable too, but nothing else.
