[openamq-dev] Threadsafe channels?

[Birju Prajapati]

Many thanks for the clearup :)

Couple of other typos:
ASL Field Table Classes in
http://www.openamq.net/doc_wireapi.txt_flat.html#TOC29
Is missing a pointer symbol before field_table in the first bit of code.

Another in http://www.openamq.org/doc_wireapi.txt_flat.html#TOC16
Content Access Methods
For each content class (Basic, File, Stream), WireAPI provides a set of
methods to access arrived and returned content:
amq_client_session_[classname]_[arrived|returned] ()
amq_client_session_[classname]_[arrived|returned]_count ()

The latter should be
amq_client_session_get_[classname]_[arrived|returned]_count ()

The protocol allows multiplexing, but OpenAMQ does not (any longer)
support it.  We used to but it made the protocol machines quite complex.
No-one used that code, and in performance tests it was no better than
one channel per connection.  So we killed it.  AMQP is over-designed in
this respect.

WireAPI only allows one?

Yes, indeed.
