497  * Return information on open files or named pipes. Only members of the
498  * Administrators or Server Operators local groups are allowed to make
499  * this call. Currently, we only support Administrators.
500  *
501  * If basepath is null, all open resources are enumerated. If basepath
502  * is non-null, only resources that have basepath as a prefix should
503  * be returned.
504  *
505  * If username is specified (non-null), only files opened by username
506  * should be returned.
507  *
508  * Notes:
509  * 1. We don't validate the servername because we would have to check
510  * all primary IPs and the ROI seems unlikely to be worth it.
511  * 2. Both basepath and username are currently ignored because both
512  * Server Manger (NT 4.0) and CMI (Windows 2000) always set them to null.
513  *
514  * The level of information requested may be one of:
515  *
516  *  2   Return the file identification number.
517  *      This level is not supported on Windows Me/98/95.
518  *
519  *  3   Return information about the file.
520  *      This level is not supported on Windows Me/98/95.
521  *
522  *  50  Windows Me/98/95:  Return information about the file.
523  *
524  * Note:
525  * If pref_max_len is unlimited and resume_handle is null, the client
526  * expects to receive all data in a single call.
527  * If we are unable to do fit all data in a single response, we would
528  * normally return ERROR_MORE_DATA with a partial list.
529  *
530  * Unfortunately, when both of these conditions occur, Server Manager
531  * pops up an error box with the message "more data available" and
532  * doesn't display any of the returned data. In this case, it is
533  * probably better to return ERROR_SUCCESS with the partial list.
534  * Windows 2000 doesn't have this problem because it always sends a
535  * non-null resume_handle.
536  *
537  * Return Values:
538  * ERROR_SUCCESS            Success
539  * ERROR_ACCESS_DENIED      Caller does not have access to this call.
540  * ERROR_INVALID_PARAMETER  One of the parameters is invalid.
541  * ERROR_INVALID_LEVEL      Unknown information level specified.
542  * ERROR_MORE_DATA          Partial date returned, more entries available.
543  * ERROR_NOT_ENOUGH_MEMORY  Insufficient memory is available.
544  * NERR_BufTooSmall         The supplied buffer is too small.
