[ace-users] ACE Thread

[Raghu Nambiath]

Hello everybody,

Iam having a question with respect to ACE. This is regarding Threads. Is
thread per connection being supported in ACE. This is with respect to
concurrent servers.

1. One main thread listens on 1 port.
2. When ever a new connection request arrives from a client, spawn a
seperate thread to start receiving messages from the same.
3. Server goes back to the listen mode.

Thanks in advance...

Raghu

Yes. We do that all the time.

Right. Please take a look at

$ACE_ROOT/tests/Process_Strategy_Test.cpp.

which demonstrates how to use the ACE_Strategy_Acceptor with different
concurrency strategies.

Thanks,

Nanbor

BTW, thanks to James Johnson, there's even an online tutorial that
illustrates how to use ACE to implement thread-per-connection. Please
see

Thanks,

Yes, indeed. Both ACE and TAO support this concurrency model.

It's trivial to do this -- all you need to do is activate() your
Svc_Handler. Check out

$ACE_ROOT/netsvcs/lib/Server_Logging_Handler_T.cpp

for an example of how to do this.

Take care,
