This task is problematic to attempt because its description is currently tied very closely to how Ada conceives of it to be done. —[[User:Dkf|Dkf]] 18:57, 12 May 2009 (UTC)
: From the birth of it I am wondering if using dbus would be possible to achieve the same purpose and being task compliant... and why not named pipe...? or simply a socket...? Is a synchronous "echo server" (like [[Echo Server]], but synchronous as said) usable in the same way a ''rendezvous'' can be used?

:: If I remember right (and it's a few years since I studied this) with the “Rendezvous” communication style:
::* The sender sends a message and waits for the receiver to reply; will only commence execution once the receiver responds.
::* The receiver can choose when to accept the message and how to respond to it.
::* Sender and receiver are synchronized (with sender idle) for the duration of the processing of the message. It is from this synchronization that the name “rendezvous” originates.
::* It has a lot in common with the communication model in [[wp:Calculus of communicating systems|CCS]], except (of course) for the fact that values are passed as arguments and returned as a result.
::* I do not remember if Ada allows accepting of messages dependent on what the values of some arguments are, but other (admittedly much more obscure) languages do allow such things within the general communications model; it's a language feature, not a communications feature.
::* I believe the sender can't formally constrain how the receiver responds.
:: Does this (rather sketchy) summary help? —[[User:Dkf|Dkf]] 08:07, 19 May 2009 (UTC)
