The only way I know to reload a binary file is like eni said rebooting pd, I believe that this process would decrease external devel'n'debug time and allow fast and clean updates.

You have to distinguish between binary and binary.

Originally binary was an adjective meaning "made of two parts" or "between two things" and similar things. Then it became a noun and began to refer to base 2 encoding. Then it referred to non-ASCII files, and then it referred also to machine code files (back in early UNIX, most non-ASCII files were machine code files)

If you want to reload .so files, it's not impossible, pd would have to keep track of each dlopen() and match it with a dlclose() when necessary. However, that's not enough to effectively have reloadable externals: the big problem is that pd doesn't have an "unsetup" function so the external cannot take appropriate actions in shutting itself down, and many externals wouldn't take it so well if you did that to them. Even worse, pd doesn't have an opposite of class_new(), so it can't remove references to code that gets unloaded. There would also have to be a way to track down objects so that they get "unloaded" in a proper way too, before the class itself gets destroyed, else that'll be a bunch of dangling pointers too.
