#pragma ?

Can anyone tell me what #pragma does? I'm trying to write DLL's and I see examples using the line:

Code:

---

#pragma comment(lib, "theDLL.lib")

---

I know that if u include that line u can call functions from the dll file, but then i see some examples do this:

Code:

---

extern "C" __declspec(dllimport) void fuction_name( );
void funtion_name();

---

Can someone tell me the details of what is happening?

THX!

My book says #pragma is specifically for implementation defined options, so its affect will be described in your compiler documentation, and any #pragma directive that isn't recognized by the compiler will be ignored.

Declaring a variable as extern implies that it is defined somewhere outside the present scope.

As far as the details of the code you posted, I have no idea. :)

Here is the reference for all the MSVC pragma's.
Enjoy.
