// sizeof(SRV_DIRECTORY_INFORMATION)

// where maxCount is the maximum number of files to return.  The +2 is
// a slop factor to account for the possibility of files that to not
// match the search attributes, and the +13 accounts for the size of
// FAT filenames.

// Note that the minimum buffer size must include the following factors in
// order to avoid the possibility of not even being able to hold one entry
// with the longest legal filename:
//

//    sizeof(UNICODE_STRING) + (MAXIMUM_FILENAME_LENGTH * sizeof(WCHAR)) + 3

// the search filename at the end of the buffer.  (The +3 is necessary to
// allow for aligning the UNICODE_STRING on a ULONG boundary.)
