Good day everyone - sorry if this is not totally Cocoa-related: if 
there's a better list for this, please let me know and accept my 
apologies in advance...

Is there any way to know the fields in a C structure, if you don't 
have the headers that define it? Or at the very least, is it possible 
to access it's field values?

Thanks!
