 @deftypefn Supplemental int vsnprintf (char *@var{buf}, size_t @var{n}, const char *@var{format}, va_list @var{ap})
 
-This function is similar to vsprintf, but it will print at most
-@var{n} characters.  On error the return value is -1, otherwise it
-returns the number of characters that would have been printed had
-@var{n} been sufficiently large, regardless of the actual value of
-@var{n}.  Note some pre-C99 system libraries do not implement this
-correctly so users cannot generally rely on the return value if the
-system version of this function is used.
