[Ace-users] [ace-users] Task name in VxWorks

[Douglas C. Schmidt]

Hi Alex,

   Thank for using the PRF.

>     ACE VERSION: 5.5

Please upgrade to ACE+TAO+CIAO x.6.1 (i.e., ACE 5.6.1, TAO 1.6.1, and
CIAO 0.6.1), which you can download from

http://download.dre.vanderbilt.edu

under the heading: "Latest Beta Kit."

The DOC groups at Washington University, UC Irvine, and Vanderbilt
University only provide "best effort" support for non-sponsors for the
latest release, as described in

http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/docs/ACE-bug-process.html

Thus, if you need more "predictable" help for earlier versions of
ACE+TAO, I recommend that you check out

http://www.dre.vanderbilt.edu/support.html

for a list of companies that will provide you with ACE+TAO commercial
support.

I don't see an easy way to make this 100% portable since the operating
systems simply have different types for thread id.  If you see a way to
do this please let us know.
