Void Pointers question

Returning a void* is syntactically fine. Post your code.

It can, you're just using it wrong. You're doing pointer arithmetic on it before the cast, rather than after the cast. Post your code.

Also, post your reasons for avoiding templates.

You need to post some code, specifically around the area where the error occurs. (Make sure to use [ source ] tags--no spaces--when you do.)

Include with the code a brief overview of the high level goal you are trying to achieve.

And muffins.

Absolutely.

I get the arithmetic now, it didn't know the size of bytes with no cast. Does the void function have to return a void pointer?, I'd much rather do arithmetic within the function. Otherwise I will also be writing to an address the amount to move the pointer.

The 'high level goal' is just a simple macro. It puts like things together while trying to optimize memory(less fragments) among other directives I can give it. It will do this and interface with a global buffer of types..

There's no such thing as a void function. Do you mean a function with a void return type? If so, then you can't return anything from it, not even a void pointer. Of course, you also failed to post code or bring muffins, so it's hard to help you.

Avoid templates?! Meaning you're using C++ and yet...
Is that from lack of experience with them, or from executable size paranoia, or because you're trying to make the life of the next programmer to maintain the code hell, or ...?
No code posted yet.

Coming up next on things to avoid ... breathing

Yes it is void*. The code is just full or syntax bugs not worth showing. I'm starting to think this would be easier typecasting a char* pointer and using it as basic strider. If I don't I will have to write a cast for each type when I could just get a stride and move it in bytes.
Or templates, which I don't understand why they don't work in a header/source file. Just seems like a distraction.

... What is the function in question supposed to do?

Higher again. Until we have code or a description of what is (supposed to be) going on there is a limit to the amount of help we can offer.

We don't care. We will probably be able to grasp what you are trying to achieve from it.

...junkies. [lol]

Are you talking about how (typically) the implementation of a class or function template must reside in the header file (either directly or indirectly)?

If so, to view this as a reason not to use templates is a mistake, IMO. Vast portions of the C++ standard library and almost all of Boost are based heavily on templates, so I think it's pretty safe to say that templates are a little more than 'a distraction' :)

I don't know that you've made it clear yet what you're actually trying to do, but maybe this would be a good opportunity to familiarize yourself with this particular feature of C++.

Hmm... whatever your intention, the answer you're looking for is "you can't do pointer arithmetic using void pointers".

The real question you should be asking is "How should I be solving this bigger problem?" Since you don't want to post source, we can't say for sure, but it likely involves a more generic (template-y) approach.

Source files are compiled.

Templates did it. Thanks for help.
