I am calling a C++ library from OpenMCL. ffigen will not generate
the interface for a C++ header file, even for functions (the .ffi
file is created, but no cdb fils are generated).
This means I have to use external-call, for which I cannot find many
One thing I would like to be able to do is pass a lisp callback to a C
++ function, much like is done with:
But if I try something like:
(external-call "_my_func" :function #'display-cb :void)
I get an error.
What is the correct way of doing this? And are there more detailed
examples of using external-call documented somewhere?
