#BASILISK II THE DYNAMIC LINK LIBRARY LIBGLIB CODE#

Rest assured, you can use MSVC and Visual Studio to do all these things.Įven though the code of the DLL is written in C++, we've used C-style interfaces for the exported functions.

#BASILISK II THE DYNAMIC LINK LIBRARY LIBGLIB HOW TO#

It doesn't show how to create a resource-only DLL, or how to use explicit linking to load DLLs at run-time rather than at load-time. The code doesn't show the use of C++ DLLs by other programming languages. This walkthrough doesn't cover some common situations. This linking lets the app call the DLL-supplied functions just like the functions in a statically linked library. The client app uses implicit linking, where Windows links the app to the DLL at load-time. It can be called from apps written in other programming languages, as long as the platform, calling conventions, and linking conventions match. This walkthrough creates two Visual Studio solutions one that builds the DLL, and one that builds the client app. The MSVC compiler implements some Microsoft-specific extensions to C++ to provide this extra information. Windows requires extra information that isn't part of the standard C++ compilation model to make these connections.

Unlike a statically linked library, Windows connects the imports in your app to the exports in a DLL at load time or at run time, instead of connecting them at link time. A client app imports the names to use those variables, functions, and resources. Like a statically linked library, a DLL exports variables, functions, and resources by name.

Use the functions and variables imported from the DLL in the console app. You'll also get an introduction to some of the programming techniques and conventions used in Windows DLLs.Īdd exported functions and variables to the DLL.Ĭreate a console app project in Visual Studio. Then you'll create a console app that uses the functions from the DLL. In this walkthrough, you'll create a DLL that implements some math functions. DLLs can even make it easier to service and extend your apps.

You can use them as a way to share code and resources, and to shrink the size of your apps. DLLs (also known as shared libraries in UNIX-based operating systems) are one of the most useful kinds of Windows components. Then it shows how to use the DLL from another C++ app. This step-by-step walkthrough shows how to use the Visual Studio IDE to create your own dynamic link library (DLL) written in Microsoft C++ (MSVC).
