- * Original:
- * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
- * A bombproof version of doprnt (sm_dopr) included.
- * Sigh.  This sort of thing is always nasty do deal with.  Note that
- * the version here does not include floating point...
- *
- * snprintf() is used instead of sprintf() as it does limit checks
- * for string length.  This covers a nasty loophole.
- *
- * The other functions are there to prevent NULL pointers from
- * causing nast effects.
