496 * PRIVATE h_AddrInSameNetwork

498 * Description:
499 * Given a target IP address and a candidate IP address (both
500 * in host byte order), return a non-zero value (1) if the
501 * candidate address is in a different network from the target
502 * address.
503 *
504 * Arguments:
505 * a_targetAddr : Target address.
506 * a_candAddr : Candidate address.
507 *
508 * Returns:
509 * 1 if the candidate address is in the same net as the target,
510 * 0 otherwise.
511 *
512 * Environment:
513 * The target and candidate addresses are both in host byte
514 * order, NOT network byte order, when passed in. We return
515 * our value as a character, since that's the type of field in
516 * the host structure, where this info will be stored.
517 *
518 * Side Effects:
519 * As advertised.

4009 * pointless, it is downright dangerous.
