Can someone please explain this?

Hi, I've been learning how to create DLL's for mIRC recently, and I saw this in the help file:

Code:

---

int __stdcall (*UnloadDll)(int mTimeout);

---

I'm new to creating DLL's, I can create them and everything, but I dont know too much to do with them, so what do the brackets around UnloadDll mean? This has gotten me totally and utterly confused. I cant seem to pull my head around this one. Any explanations would be greatly appreciated.

UnloadDll is a pointer to a function. That function takes an int parameter (which will get used as a timeout if the parameter name is accurate), and it will return an int.

The __stdcall is a compiler specific extension to help it figure out the right thing to do when calling across language boundaries (its called a calling convention).
