general array in C

[Cyn]

Hi,
I want to create a general array structure which can hold all types.
Something like this:

struct ARRAY
{
void **array;
size_t size;
};

Work nice to store pointers to structures in it but what is a good way to be
able to both store pointers to structures and primitive types in it?

The code is incomplete but I can provide full source code
self-contained (actually it throws exceptions).

Be sure to read that entire thread.

I did.

Could you show me the useless casts in the posted code? I do not say
that the code is perfect, but I do not see useless casts ((void*)
casts are there for information)

>it deliberately doesn't check for allocation errors,

Could you show me what allow you to say that?

>and it *isn't C*. (I think it depends on gcc-specific extensions.)

This is pure C89 code (inline vanishes if OOC_ISO_C < OOC_ISO_C99).

May I suggest you to read again the code?

My apologies. I was referring to the code in the article that started
the thread:

<http://groups.google.c om/group/comp.lang.c/msg/9c9c34004ae180b 5>

not to the code that you posted later:

We must do something. This is something. Therefore, we must do this.
