'Base class' shared libraries in C?
I am trying to implement some C++ functionality in C.
Suppose I have several libraries that share behavior and properties, such as
version, working directory, and so on. I want other libraries to extend
this behavior without having to duplicate any code. For instance:
typedef struct base
typedef struct foo
typedef struct bar
base_get_version(base_t *, char *);
base_get_path(base_t *, char *);
foo_one_method(foo_t *, int data);
foo_two_method(foo_t *, int data);
bar_one_method(bar_t *, int data);
bar_two_method(bar_t *, int data);
I want the derived modules to link with the base library, so that my
application can link with only the derived modules and still be able to call
the base functions without having to link to that library or call 'wrapper'
functions in the derived modules.
Is there a way to do this?
