My manpage says:
>Return value
> These functions return the number of characters printed
> (not including the trailing `\0' used to end output to
> strings). snprintf and vsnprintf do not write more than
> size bytes (including the trailing '\0'), and return -1 if
> the output was truncated due to this limit. (Thus until
> glibc 2.0.6. Since glibc 2.1 these functions follow the
> C99 standard and return the number of characters (exclud-
> ing the trailing '\0') which would have been written to
> the final string if enough space had been available.)
