How do I go about writing a dll for pinging?

This question admittedly sounds stupid, however, I'm trying to create a dll for another application that I didn't build that only accepts unmanaged C/C++ dlls. This is for hooking into a game and pinging clients that connect to the game (the application I didn't build). I've been looking at tons and tons of stuff on google, but I can't find anything that seems to be the holy grail.

Do I use ICMP or TCP for this? Is it possible to spam a client with ping requests and therefore be seen as a threat, or to accidentally do denial of service sort of attack on clients using ICMP?

Any help would be appreciated.

An interesting idea, using the C# class, I'll check into it and see if it's possible for this application.

The following might help.
Note however that you can use managed code with unmanaged code; right? So you should be able to use the .Net Ping class. My Ping Tool in C# should make that easy.

Perhaps I didn't make the problem obvious. I guess I added too many details. Forget the dll aspect, I can manage that fine, but the real problem is the networking portion of this project. I'm looking for a mere general direction to start researching the answer, I'm not looking to be merely handed the answer. I have no real experience with anything networking related, whereas I can manage a few dlls in visual C++ with no real trouble.

Are you experienced with C++? Are you familiar with DLLs? When I say DLL, I mean a real DLL; not a COM object or anything like that. If the answer to all that is yes, then you would have no problem. You are having a problem because you are unable to see a tree in a forest of trees.

There are abundant articles about pinging using the Windows API. None of them will be useful if you don't know how to write a DLL. Are you sure you are familiar with C++ and DLLs enough for doing this, or are you going to need to get someone else to do it all for you? Are you ready to do some learning?
