A normal user could think this advice applies to normal shard libraries aka dynamically loaded libraries which in my opinion is not the case. What do Nini-howto overlook?

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.

This is a strong architectural design decision.
