Hi Roy,

RJT> there,
TVFS implements a Logical drive under OS/2 that confirms to a UNIX style file
system but to do this it needs to "massage" things so that the differences
between the UNIX world and the other environments the files can come from do
not cause problems. One of theother nice things about TVFS is that in a LAN
environment, different platforms on the LAN can provide various file systems
as segmetns of the overall TCFS logical drive, and this is hidden from
whoever is accessing the drive.
EG, a file stored on an OS/2 HPFS partition is stored as case retentive, but
NOT case dependant. A UNIX file system is case retentive and is also case
dependant, so immediately you have a potential conflict, depending on WHO is
accessing the file and what they expect to happen. Consider also a FAT
partition where filenames are 8.3 and all upper-case. With TVFS you MUST
supply the 8.3 name in all upper case to be able to access it. Ov course
because FAT was never designed to have UNIX access rights applied to it, TVFS
has to fudge around it, the same with other file systems and of course
whatever LAN environments is sharing the component of the TVFS.
Pick up a copy of it and read the DOC,s it makes you think about sharing
files over a LAN in a completely new way........;-)
