Hi
I just released my article on the wiki:
http://wiki.amigaos.net/wiki/How_to_cre ... S4_library
Don't hesitate to correct my approximated english and my technical errors and gaps.
I hope it will be of some help for newbies.

I guess using globals is bad, but it would allow to minimize the code change between the direct access out of the library for development and debugging, and the access through the library for release.

That's didn't quite compute... what do you mean here?

I developped my toolkit as regular ...

Hi again
I'm writing a simple step by step howto for the wiki and I'm wondering about a few things.

- In libInit I get a struct Interface *exec
May I just keep it or should I Obtain it ?

- the Utility interface sample in libInit stores the pointers in the libBase
What are the risks if I keep the ...

Thanks for the explanation.
I'll put it in the wiki too.

Ok, I've done it and, surprise, I can use newlib !

just a note about something I noticed in my logs:
- the first time I open a new build of my sample library, libInit() is called, then Obtain() is called twice,
- when I close the library, only one call of Release() is done,
- when I open the ...

Thank you for the detailed advices.
I'll keep it simple as you described it and make some tests.
In fact I shoudn't spend so much time about a case which will hardly happen, but I like to do the things right the first time sothat I don't have to come back at it later.

Once again, a big thank you ...

I was thinking about the cleaning instructions generated in libExpunge() by IDLTool:

libBase->IExec->Remove((struct Node *)libBase);
libBase->IExec->DeleteLibrary((struct Library *)libBase);


I thought it was the cleanup of the LibraryBase I get in libInit(), was I wrong ?
And is there ...

Thank you Tonyw

I guessed I have to return NULL, as that's what happens for any library. But my wonder is: should I clean up the LibraryBase or will libExpunge() be called automagically to do it ?

Here is a new question:
How should I handle an error during libInit() (example: can't open another library) and abort cleanly my library opening sothat the user application get informed ?

TIA

Ok, thank you both for the support.
Once my library is validated, I will contribute to the wiki.
