Library is cached if loaded multiple times

[TobiasGrothmann]

Hi there,

I have a little bit of a special use-case and I don't know very much about loading dynamic libraries at runtime.

I am trying to:

• Load a dylib at runtime -> works
• get a function -> works
• call said function and use its return value -> works

Now comes the part that doesn't work:

• Compile a cargo project at runtime and generate a new dylib -> works
• Load the library again -> not sure if that really works
• get and call the changed function -> definitely doesn't work

The problem is, that I still somehow get the old function and get the old return value from it. How can I force it to unload and reload the library?
