class test {
public:
test();
void tester(int a);
private:
int s;
};
Interesting thought....

Hello.
I am having this thought... Can i combine a bunch of functions in a sort of an object, i mean under "C", and pure "C".
Basically, translate this to "C":
Thanks in advance!
Function Pointers. Take a look at the Quake 3 source. Its done a lot of times, obviously you wont have inheritance and such, but you can cheat.
Also, my syntax may be wrong, I don't frequently use function pointers.
struct test{ void (*test)(); void (*tester)(int a); int s;}Also, my syntax may be wrong, I don't frequently use function pointers.
The way to do that is to have a series of global functions which act on a handle to the instance (either a pointer to a struct, or an opaque value).

Can you please explain a bit more...

struct test{ int s;}void test_test(test& object){ s = 0; return;}void test_tester(test& object, int a){ s = a; // ? return;}Quote:Original post by Ancient Spirit
i dont think u can use the "&" in "C"
picky picky people, this is what I get for being a pure C++ programmer
struct test{ int s;};void test_test(test* object){ object->s = 0; return;}void test_tester(test* object, int a){ object->s = a; // ? return;}And I fixed a bug aswell. Now fixed the real bug.

No, you can't, but you can replace it by a pointer.
[edit] Fixed at time of writing.
[edit2] And don't forget to actually use the pointer... ->
jfl.

Here are a couple of links that might help.

If you want to get an idea of how vtables are constructed, if you have access to a Windows based compiler, open the iunknown.h in a text editor and examine what it does with structures, forward references, and function pointers. You might also have to search for macro definitions in other headers.
