CodeWarrior Sending and receiving messages between two apps

[pfuentes69]

Hello
I’d like to send messages (short commands) between two applications.
It may be TCP/IP or AppleTalk, whatever is easier, but it should be C or C++.

I don’t really know where to start… any hint?

txs!

Apple Events?

Yes, this is pretty much what Apple Events were designed for.

Just to clarify that I mean messaging between apps running in different computers…

Googling for “Apple Events” is not a good strategy… some link would be appreciated

It's still Apple Events because they can go from Mac to Mac. The facility you want is the PPC Toolbox (not PowerPC: Process-to-Process Communication).

Thanks.
This points me to some direction... Although I foresee a big challenge to build a working C application using the Toolbox documentation with those illustrative snippets of Pascal code... If I'm lucky I will find maybe a full client/server basic example.

I‘d also vote for AppleEvents, but ATP or ADSP might be alternatives.

If you control the applications, you could always just register a gestalt value that contains a pointer to a buffer or callback methods.

Edit: I now see you want to do it over a network and not within the same machine.

I appreciate your inputs… I just wish I could understand a word

It looks like OP has asked the same question on 68KMLA, I have posted my thoughts there:

Years ago when I was a full time Mac programmer I used the interapplication communication architecture. I can’t remember the details but it was apple event based. Found this article
