Loading a third party dll in visual c++/qt application

Question

I have third party dlls that I need to use with my application. The interface is defined in the third party dlls and I have to make the interface call from my application. I have the function prototype of the interface, but no lib files or header files. It looks like loadlibrary should be used, but is it possible without the header files ? Is there a way to generate such header files? Would also greatly appreciate some explanation for the loadlibrary, as I am still grasping the idea yet. Thanks!

Answer 1

您可以使用QLibrary :: resolve（） （或其静态便利兄弟）在DLL中查找符号并调用它。

Answer 2

You load the library with the API function LoadLibrary . After loading the DLL you use GetProcAddress to get the entry point for a specific function.

If it's a C++ library, you may have to care for the decorated names. The tools dumpbin and undname may help to identify what is really exported by the DLL.
