5.2 Extended File Specifications
Because mixed UNIX and OpenVMS style extended file names are not yet
supported by the Compaq C RTL, you may be required to use UNIX style
syntax when interacting with Java applications or FastTrack or Apache Server.
For example, you may want to modify a root to which you append additional
directories or a file name.
The following example illustrates sample mixed UNIX and OpenVMS style file
names that are not supported on OpenVMS Alpha Version 7.3:
doc/foo.bar.bar
./tmp/foo.bar.b^_ar
~foo^.bar
However, you can modify the last example so that it will work as an OpenVMS
extended file name that has a tilde (~) as the first character. Precede the leading
tilde (~) with the extended file specifications escape character (^). For example:
^~foo^.bar
See the OpenVMS Guide to Extended File Specifications for more information
about using the tilde (~) in OpenVMS extended file names.
In addition, C RTL functions that return file names do not work correctly if any
of the following conditions are true:
• The VMS file specification contains ODS-5 characters.
• The VMS file specification contains a directory name in Directory ID (DID)
format.
• The VMS file specification contains a file name in File ID (FID) format.
• The file specification is larger than the receiving buffer.
If any of the above conditions is true, the following C RTL routines will fail:
getname()
fgetname()
getcwd()
decc$from_vms()
decc$translate_vms()
Files meeting any of the above conditions will be skipped by the following C RTL
routines:
ftw()
readdir()
These mixed UNIX and OpenVMS style file names will be supported in a future
release of Compaq C RTL for OpenVMS.
5.3 External Authentication
This section contains release notes pertaining to external authentication.
External authentication is an optional feature introduced in OpenVMS Version
7.1 that enables OpenVMS systems to authenticate designated users using their
external user IDs and passwords.
Starting with OpenVMS Version 7.2, if you are running DECwindows and you
want a DECwindows user to be externally authenticated, you must be running
DECwindows Version 1.2-4 or later and Advanced Server for OpenVMS, and
meet any requirements outlined in the Advanced Server for OpenVMS Server
