Using the dynamic library in a program

Now that we have created a dynamic library and installed it on our system, it's time to try it out in a program. We have actually been using dynamic libraries without even thinking about it since the very beginning of this book. Functions such as printf() and so on are all part of the standard library. In the The what and why of libraries recipe from earlier in this chapter, we used another dynamic library called cURL. In this recipe, we'll use our very own library that we installed in the previous recipe.

Knowing how to use custom libraries will enable you to use other developers' code, which will speed up the development process. There's often no need to reinvent the wheel.

Getting ready

For this recipe, we'll need the temperature.c code from the Using a static library recipe earlier in this chapter. That program will use the dynamic library. You'll also need to complete the previous recipe before attempting...
