Re: Asynchronous IO api

[Bruce Vining <bvining@xxxxxxxxxx>]

Scott,

If by asynchronous IO you are refering to the Qso* socket APIs then
consider yourself gently corrected :)

While the Information Center examples refer to and use a multi-threaded
server environment you can also use asynchronout IO from a single threaded
environment and still obtain the benefits that the APIs provide.

Hello,

I believe that the Async I/O functions require a language that can support
threads.  Since RPG cannot run in multiple threads, you can't use this API
in RPG.

Someone please correct me if I'm wrong.

The normal sockets API can be used without problems in RPG -- just the
Async I/O functions won't work without a threaded language.  (I don't
consider the Async I/O functions to be "normal" sockets functions since
they don't exist on other platforms, whereas the basic sockets functions,
socket(), connect(), bind(), listen(), accept(), select(), etc appear on
every platform that I know of, and are a "de-facto standard.")

IF you want information about using the normal sockets functions in ILE
RPG, you can read about them on my web site:
