/* These APIs aren't really part of the error implementation, but
   often needed to format error messages; the native C lib APIs are
   not available on all platforms, which is why we provide emulations
   for those platforms in Python/mysnprintf.c,
   WARNING:  The return value of snprintf varies across platforms; do
   not rely on any particular behavior; eventually the C99 defn may
   be reliable.
