Re: Is Objective-C loaded?

I've tried different methods of doing this (oddly enough trying to create a CFBundle with /usr/lib/libobjc.dylib returns NULL).

I used NSIsSymbolLoaded to find out if objc_msgSend is available and if it is, I try to call some other function in the objective-c runtime (not ready to call obc_msgSend yet) but when I do, it crashes the application if the objective c runtime has been loaded, but not used (or initialized or something).

These are edge cases that they crash in, but its enough to cause some trouble. Is there anyway to be sure that I can call Obj-C functions (and then AppKit methods in the process)

Is it possible to find out if any of the objective c frameworks have loaded into an application? Also, what kind of functions require the objective c framework to be loaded? Do the functions in the objc.h header require anything?

I ask because I am developing a plugin that could be in either a cocoa or carbon application and I'd like not to call *any* objective-c code when inside the carbon application incase it tries to unload the plugin since objective-c code can't be unloaded from an application.
