What is a DLL?

A DLL (Dynamically Linked Library) is a file executed by a program (EXE). A DLL cannot run by itself and must have a parent program to run. A DLL can save RAM usage by being executed by two programs at the same time. Unfortunately, DLLs can only be run with a windows system.

Creating a DLL

I am only familar with creating a DLL with C and C++, so I can't help all you people using other programming languages, such as Fortan. Most C/C++ compilers have the ability to create a DLL Project. Make your functions, classes, and structures; defining functions like this:

__declspec(dllexport) int CALLBACK myfunction(int arguments) { //C/C++ code here }

Compile the DLL.

Now create a program to run the DLL. IT MUST BE A WINDOWS APPLICATION! Include the header file (.h) in program like this:

1. include "myDirectory/myHeader.h"

Then insert the library (.a/.lib) that was created when you compiled the DLL. Put the DLL in the same directory as the program. Now compile your program. You just created your own DLL!
