foreign-funcall-pointer (pointer options &rest args)

pointer -- A foreign pointer.
arg-type -- A foreign type.
arg -- An argument of type arg-type.
return-type -- A foreign type, :void by default.
convention -- One of :cdecl (default) or :stdcall.

A lisp object.

The foreign-funcall-pointer macro is a primitive for calling foreign functions.

Note: The return value of foreign-funcall-pointer on functions with a :void return type is still undefined.

Implementation-specific Notes

Corman Lisp does not support foreign-funcall-pointer. On implementations that do not support foreign-funcall-pointer the symbol cffi-sys::no-foreign-funcall will be present in *features*. Note: in these Lisps you can still use the defcfun interface.
