Isn't this possible?

cwrap.h:

struct Foo_Obj; //fwd declaration

#ifdef __cplusplus
extern "C" {
#endif

struct Foo_Obj* foo_obj_create();
void foo_obj_dosomething(Foo_Obj* obj);
void foo_obj_delete(Foo_Obj* obj);

#ifdef __cplusplus
}
#endif

cwrap.cpp:

#include "foo.hpp"

struct Foo_Obj {
    FooLib::Obj realthing;
};

extern "C" {

struct Foo_Obj* foo_obj_create() {
    return new Foo_Obj;
}
void foo_obj_delete(struct Foo_Obj* obj) {
    delete obj;
}
void foo_obj_dosomething(struct Foo_Obj* obj) {
    obj->realthing.dosomething();
}

} //extern "C"
