GNU ObjC runtime question

[Marcus Müller]

Hi,

I'm currently porting some frameworks from OS X to GNUstep. 
Unfortunately I'm not very familiar with the GNU ObjC runtime but 
there's one thing I need to know in order to finish the porting. In the 
NeXT runtime there's something like this:

int objc_getClassList(buffer, bufferLen)

We use it to find out about all the classes currently loaded into the 
runtime. In a special C function we can then identify all subclasses of 
a specific class in the runtime. Is there a similar function available 
in the GNU runtime? Is there another possibility of finding out all 
currently loaded subclasses of a specific class?

Thanks in advance,

  Marcus
