Shared DLL?

From what I understand, you can't, or at least shan't :-)

Each executable that runs has its own memory addressing space. That is, two executables could simultaneously have pointers to 0x3003fa12, but they actually point to separate areas of physical (or virtual) memory. The operating system makes sure that you don't overstep your bounds into other peoples' memory. Poking around outside your space is likely to result in segmentation faults (read: catastrophic failure).

The answer is to have some kind of third party communicate between the two. A database (probably not for a game), a TCP/IP socket connection (very reliable and fast on the localhost), or something like that.

Correct me if I'm wrong.

Well your right about the memory I knew about that problem already. However I was hoping to keep this as simple as possible, and did not want to have to resort to some TCP sockets, or file access.

Here's a Microsoft example of how to share memory between processes: Creating Named Shared Memory.

There are other ways to pass data between applications. The topic is named Interprocess Communications. You can find the details at that link.

Here's a very simplistic method of sharing memory in a DLL:



Shared memory blocks in code have to be initialized -- so when you declare the variables you must also assign them to something.
