In practice, it is often easier just to use @code{asprintf}, below.
@strong{Attention:} In the GNU C library version 2.0 the return value
is the number of characters stored, not including the terminating null.
If this value equals @code{@var{size} - 1}, then there was not enough
space in @var{s} for all the output. This change was necessary with
the adoption of snprintf by ISO C99.
@strong{Attention:} In versions of the GNU C library prior to 2.1 the
return value is the number of characters stored, not including the
terminating null; unless there was not enough space in @var{s} to
store the result in which case @code{-1} is returned. This was
changed in order to comply with the @w{ISO C99} standard.
