Software running under Microsoft Windows Software running under Microsoft Windows makes extensive use of "dynamic link makes extensive use of "dynamic link libraries." A dynamic link library (DLL) is a libraries." A dynamic link library (DLL) is a set of executable code that has the set of executable code that has the following properties:following properties: – the code is loaded at run time only when the code is loaded at run time only when

it is actually needed (dynamically linked) it is actually needed (dynamically linked) – it is group of functions for accomplishing it is group of functions for accomplishing

To create code that uses DLL's, you To create code that uses DLL's, you typically need 3 types of software: typically need 3 types of software: – header files (*.h) header files (*.h)

these files contain data type definitions these files contain data type definitions and function prototypes that allow your and function prototypes that allow your code to be code to be compiledcompiled correctly. correctly.
