Welcome to ACE! 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
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

Sure - you can use the Asynchronous Completion Token pattern for this.
Please see the discussion of this pattern in the POSA2 book
<www.cs.wustl.edu/~schmidt/POSA/POSA2/> for details.

Please see Chapter 8 of C++NPv2 <www.cs.wustl.edu/~schmidt/ACE/book2/>
for an overview of the Proactor pattern.
