[ace-users] message transfer between processes.

[Douglas C. Schmidt]

Hi Kim,

To ensure that we have proper version/platform/compiler information,
please make sure you fill out the appropriate problem report form (PRF),
which is in

$ACE_ROOT/PROBLEM-REPORT-FORM
$TAO_ROOT/PROBLEM-REPORT-FORM

or in

$ACE_ROOT/BUG-REPORT-FORM
$TAO_ROOT/BUG-REPORT-FORM

in older versions of ACE+TAO.  Make sure to include this information
when asking any questions about ACE+TAO since otherwise we have to
"guess" what version/platform/compiler/options you've using, which is
very error-prone and slows down our responsiveness.  If you don't use
the PRF, therefore, it is less likely that someone from the core
ACE+TAO developer team will be able to answer your question.
Naturally, we encourage and appreciate other members of the ACE+TAO
user community who can respond to questions that they have the answers
to.

I recommend you use ACE_SOCK_Stream/ACE_SOCK_Acceptor/ACE_SOCK_Connector
and ACE_Acceptor/ACE_Connector, as shown in C++NPv1/C++NPv2
<www.cs.wustl.edu/~schmidt/ACE/>.

ACE_SPIPE should work fine.  Please see

ACE_ROOT/examples/Connection/blocking/

for an example to ry.

reads, and not different process space.

Right - it's not what you want to use..

 Found that it stands for =D2User pipe=D3.

Right.

> What is the UPIPE capability compared to SPIPE ?

You don't want to use UPIPE for what you're trying to do.

Take care,
