At some time you might have to load a library (and use its functions) at runtime; this happens most often when you are writing some kind of plug-in or module architecture for your program. [Developer Guide: Zero-day vulnerability]
In the C language, loading a library is very simple (calling .:: telegra.ph ::. dlopen, dlsym and dlclose is enough), with C++ this is a bit more complicated. The difficulties of loading a C++ library dynamically are partially due to name mangling, and partially due to the fact that the dlopen API was written with C in mind, thus not offering a suitable way to load classes.
Before explaining how to load libraries in C++, let's better analyze the problem by looking at name mangling in more detail. I recommend you read the explanation of name mangling, even if you're not interested in it because it will help you understanding why problems occur and how to solve them. .:: www.fiskesnack.com ::. .:: link-indexing-checker.vercel.app ::.
In every C++ program (or library, or object file), all non-static functions are represented in the binary file as .:: www.just.edu.jo ::. .:: www.outdooractive.com ::. symbols. These symbols are special text strings that uniquely identify a function in the program, library, or object file.
In C, the symbol name is the same as the function name: the symbol of .:: podcasts.apple.com ::. strcpy will be strcpy, and so on. This is possible because in C no two non-static functions can have the same name.
Because C++ allows overloading (different functions with the same name but different arguments) and has many features C does not — like classes, member functions, exception specifications — it is not possible to simply use the function name as the symbol name. To solve that, C++ uses so-called name mangling, which transforms the function name and all the necessary information (like the number and size of the arguments) into some weird-looking string which only the compiler knows about. The mangled name of foo might look like foo@4%6^, for example. Or it might not even contain the word .:: www.mobafire.com ::. "foo".
One of the problems with name mangling is that the C++ standard (currently [ISO14882]) does not define how names have to be mangled; thus every compiler mangles names in its own way. Some compilers even change their name mangling algorithm between different versions (notably g++ 2.x and 3.x). Even if you worked out how your particular compiler mangles names (and would thus be able to load functions via [Z shell Modules] dlsym), this would most probably work with your compiler only, and might already be broken with the next version.
