Hi Richard,

Thank you for your comment. You are totally right, but this was only a small example what I made after a long learning period :-)

But I would like to know, if I have for example a small C++ library, within the classes are in a custom name space, how should I write my C wrapper to use those classes?

Thank you and all the best,

Kilato Somostetoi

Hi,

maybe it is not the best place to ask but at this moment I have no other idea where to go. This question is just a preamble for all the comming, BOOST related, questions of mine.

So, I have a C++ class, the Apple, at the moment in the std namespace:

My question is, if I want to move my Apple class in a custom namespace, garden, how must I modify my C header and code file?

Thank you and all the best,

Since your C file only deals with the structure via pointers to void, moving the class into a name space will have no effect.

Note, that the functions you are declaring to return/take pointers to void, really do return/take pointers to void, and the functions do the casting to Apple* inside.

The thing to note is that by definition, a pointer to ANY type/object can be converted to a pointer to void and back to its original type and it will point to the same object.
