C++ dlopen mini HOWTO. Aaron Isotton.. $Id: C++-dlopen- ,v /12/08 aisotton Exp $. C users will need to include the header file to use this API. dynamically loaded (DL) libraries should also consult the “C++ dlopen mini- HOWTO”. Shared Library Mini-Tutorial A shared library is a binary file that contains a set of callable C functions. Visit the dlopen man page for more information.

Shared Library Mini-Tutorial
The original question ,ini-howto about shared libraries only via comments did we find it was about plugin shared libraries. Anything specific to a component must be reachable through that API, in an identical manner from component to component.
Using it across several platforms without issues. Sign up using Facebook. Martin York k 66 BTW on Linux you can practically dlopen a big lot of plugins see my manydl.
Read the GC handbook for the terminology. Of course, I have used the search but have not found any directly linked answer. It is a pain for mangled names.
Get the name of the component or other details about it Get the number of how many inputs or outputs the component exposes Interrogate a component about a particular input our output Connect inputs and outputs together and others And that’s just for setting up your graph.
The composition of functions should be done during runtime. If the compiler is upgraded something bigger has happened I am re-build all my libraries anyway. But dlo;en should consider the cons to exposing a C extern “C” interface.
Later, one could think of adding a GUI. These containers can also hold other components cf.
Use the concepts, examples and information at your own risk. There are variants or mixes of those approaches. Sign up or log in Sign up using Google. Loki I see what you’re saying, but to me I’ve always found that using extern “C” for exactly this reason has been worth it; I don’t have to look at the symbols in the binaries so I can look them up at runtime, and if I have say configuration files which refer to these names I don’t have to worry about them changing if we change compilers.
Each function may have some inputs and return some outputs depending on the underlying physical description, e. It is not necessary to dive deeper into the framework’s capabilities because my problem is much more general. Therefore, the framework provides a container class.

The difference will be when you manually use dlsym to resolve the symbol miin-howto. Each component will need to implement a set of functions to do stuff like: Three Easy Pieces for a good overview. The document was last updated in Using extern “C” does more than that.
This is a strong architectural design decision.
