: I agree.
These functions return the number of characters printed (not including
the trailing `\0' used to end output to strings).
...
Snprintf() and vsnprintf() will write at most size-1 of the characters
printed into the output string (the size'th character then gets the ter-
minating `\0'); if the return value is greater than or equal to the size
argument, the string was too short and some of the printed characters
were discarded.
It seems to fairly clearly imply that it will return the number of
characters that would have been copied to the string, if it was long
enough.... The part after the ';' implies this. I'm not sure how it
could be clearer.
