+@deftypefn Supplemental int snprintf (char *@var{buf}, size_t @var{n}, const char *@var{format}, ...)
+
+This function is similar to sprintf, 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.
