Well, I asked a question similair to this, except I was going to reinvent
the wheel and load the libraries at run time myself, after a few days
playing with elf headers, section headers and the like, I found out how
much of a b*tch it would be, I asked about it, and dl is the answer I got.
works marvelously, compile the object shared, and use dlopen(), dlsym(),
etc.. to manipulate it at run time. man dlopen, it'll tell ya all you need
to know.
