[Ace-users] [ace-users] ACE_RW_Process_Mutex NOT WORKING

Hi,

Thanks for using the PRF.

>> ACE VERSION: 5.5.8

BTW, please upgrade to ACE+TAO+CIAO x.6.3 (i.e., ACE 5.6.3, TAO 1.6.3,
and CIAO 0.6.3), 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 think there are any examples of ACE_RW_Process_Mutex, so I
recommend you make a copy of 

ACE_ROOT/tests/Process_Mutex_Test.cpp

and update it to use ACE_RW_Process_Mutex.  Again, if you need more
help, 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.

Thanks,

        Doug
