Re: DSM example (was Using a timeout with display files)

Giday Frank,

Just curious if you would share a few use cases of your utility ?

I can see a lot of great work but I am not having the light bulb moment as
to the problem the solution provides.

Cheers

Don

Hi Patrik

DSM example program. DSMFD.

I have this code on GITHUB. (Is it just me or is GITHUB so very very
difficult to use?)
https://github.com/FrankKolmann/FranksRPG

It is a program that shows on a screen what a DDS file looks like using
the compiled object.
It uses DSM to show. Also there is a progam that uses the QDFDRTVFD api
to get the DDS info.

Regards
Frank

I've been dealing with the DSM documentation, but this is barely the

API prototypes and the several data structures and constant values that
these use. There are no significant examples and what I've found on the
Web is also poor material.

So it's not just me. :-) Good to know!

I'll have to wrap up my sleeves and try.

I'd love to see some DSM examples somewhen, if you're willing to share

your insights!

Since the input buffer is still there, that's the right moment to

invoke the *QsnReadImm* API which is a non-AID-generating read input from
the screen, and that should probably bring me the data that I'm expecting:
the one the user may have typed in.

This proves (in a twisted way) my guts feeling of "there must be a

possibility to do this". You know, the OS can set the message waiting
indicator on a terminal at any time, without intervention from the
currently running application. This made me think there *must* be an
asynchronous way to obtain data from the terminal without any read or
write in the usual way.
