|
|
* Notes from the fringe... <ptucker@sympatico.ca>
|
|
*
|
|
* Clipper is a bit schizoid with the treatment of file attributes, but we've
|
|
* emulated that weirdness here for your viewing amusement.
|
|
*
|
|
* In Clippers' homeworld of DOS, there are 5 basic attributes: 'A'rchive,
|
|
* 'H'idden, 'S'ystem, 'R'eadonly and 'D'irectory. In addition, a file can
|
|
* have no attributes, and only 1 file per physical partition can have the
|
|
* 'V'olume label.
|
|
*
|
|
* For a given file request, it is implied that the attribute mask includes
|
|
* all attributes except 'H'idden, 'S'ystem, 'D'irectory and 'V'olume.
|
|
* The returned file list will always include (for instance) 'R'eadOnly files
|
|
* unless they also happen to be 'H'idden and that attribute was not requested.
|
|
*
|
|
* "V" is a special case - you will get back the entry that describes the
|
|
* volume label for the drive implied by the filemask.
|
|
*
|
|
* Differences from the 'standard' (where supported):
|
|
* - Filenames will be returned in the same case as they are stored in the
|
|
* directory. Clipper (and VO too) will convert the names to upper case
|
|
* - Filenames will be the full filename as supported by the OS in use.
|
|
* - There are a number of additional file attributes returned.
|
|
* They are:
|
|
* 'I' - DEVICE File is a device
|
|
* 'T' - TEMPORARY File is a Temporary file
|
|
* 'P' - SPARSE File is Sparse
|
|
* 'L' - REPARSE File/Dir is a reparse point
|
|
* 'C' - COMPRESSED File/Dir is compressed
|
|
* 'O' - OFFLINE File/Dir is not online
|
|
* 'X' - NOTINDEXED Exclude File/Dir from Indexing Service
|
|
* 'E' - ENCRYPTED File/Dir is Encrypted
|
|
* 'M' - VOLCOMP Volume Supports Compression
|
|
* - Clipper can sometimes drop the ReadOnly indication of directories.
|
|
* Harbour detects this correctly.
|
|
*
|
|
* TODO: - check that path support vis stat works on all platforms
|
|
* - UNC Support? ie: dir \\myserver\root
