540 *
541 * Return information on open files or named pipes. Only members of the
542 * Administrators or Server Operators local groups are allowed to make
543 * this call. Currently, we only support Administrators.
544 *
545 * If basepath is null, all open resources are enumerated. If basepath
546 * is non-null, only resources that have basepath as a prefix should
547 * be returned.
548 *
549 * If username is specified (non-null), only files opened by username
550 * should be returned.
551 *
552 * Notes:
553 * 1. We don't validate the servername because we would have to check
554 * all primary IPs and the ROI seems unlikely to be worth it.
555 * 2. Both basepath and username are currently ignored because both
556 * Server Manger (NT 4.0) and CMI (Windows 2000) always set them to null.
557 *
558 * The level of information requested may be one of:
559 *
560 * 2 Return the file identification number.
561 * This level is not supported on Windows Me/98/95.
562 *
563 * 3 Return information about the file.
564 * This level is not supported on Windows Me/98/95.
565 *
566 * 50 Windows Me/98/95: Return information about the file.
567 *
568 * Note:
569 * If pref_max_len is unlimited and resume_handle is null, the client
570 * expects to receive all data in a single call.
571 * If we are unable to do fit all data in a single response, we would
572 * normally return ERROR_MORE_DATA with a partial list.
573 *
574 * Unfortunately, when both of these conditions occur, Server Manager
575 * pops up an error box with the message "more data available" and
576 * doesn't display any of the returned data. In this case, it is
577 * probably better to return ERROR_SUCCESS with the partial list.
578 * Windows 2000 doesn't have this problem because it always sends a
579 * non-null resume_handle.
580 *
581 * Return Values:
582 * ERROR_SUCCESS Success
583 * ERROR_ACCESS_DENIED Caller does not have access to this call.
584 * ERROR_INVALID_PARAMETER One of the parameters is invalid.
585 * ERROR_INVALID_LEVEL Unknown information level specified.
586 * ERROR_MORE_DATA Partial date returned, more entries available.
587 * ERROR_NOT_ENOUGH_MEMORY Insufficient memory is available.
588 * NERR_BufTooSmall The supplied buffer is too small.
