I'm not sure this can be done reliably, imagine for instance that someone may load libraries in their initialization file *before* loading cffi which would lead to incongruities between the lisp implementation and cffi; we should see first how many of the supported implementations have a means to see which foreign libraries have been loaded. on CMUCL there's SYS::*GLOBAL-TABLE*, on SBCL there's SB-ALIEN::*SHARED-OBJECTS* but I don't know about the others
UNLOAD-FOREIGN-LIBRARY too, it's in the TODO list I think.
You're welcome to tackle that TODO item. :-)
I'll see what I can do
