C for Blitzers

This tutorial attempts to show the basics of working with C in your BlitzMax programs. BlitzMax manual/help has a section titled “Interfacing with C and other languages”, but I find it short and confusing.

Please let me know of any errors or if I missed something important.

I've always wondered how to do this. Very useful. Thanks!

Thanks!

This will come in handy :)

This is pretty cool, and good to know. Might have to experiment with osx screensavers again :-)

What about more complex Max objects? (Types that have Methods, Functions and many different types of Fields)

EDIT: Or, I guess more importantly, what about programmer-defined objects from C to Max?

Fields can be accessed in (their source code) order, no matter how many there are. With respect to Functions, Types are just namespaces; TType.Func could be accessed using _bb_TType_Func from C. I don't know about Methods - that could be complicated due to inheritance etc.



If you mean objects of C++ classes, I don't use C++, but you might want to see this tutorial by skidracer: Importing C++ / STL tutorial. If you mean C structs - they are just a way of describing what a block of memory means. A pointer to a structure is still a pointer to raw memory.

Hmm... I think I'll write at least one more part on objects and look into methods.

Yeah, I meant to say C/C++ classes to Max Types.

I'd never seen skidracer's tutorial, will study..

Thank you very much !

This is a well appreciated documentation :)
Finally I will be able to use some of the C specificities.

YEAH !
