What is the purpose of this function argument?

In the following code pertaining to DLLs, what is the purpose of the second argument of GetProcAddress()?

Code:

---

_dllFunction = ( dllFunction )GetProcAddress( hInstLibrary, "secondArg" );

---

Thanks in advance,

I'm confused...

So, the second argument has something to do with the .def file that lists the exports of the dll? MSDN is sometimes written in a manner where someone is assumed to know more than he/she actually might know...

it's the name of the exported function whose address is being returned
