Perhaps I'm not being clear enough... perhaps and example will help.
Put this lines in a 'foo.pyx' file anc cythonize it
# ---------------
cdef public class Foo [object PyFoo, type PyFoo_Type]:
pass
cdef api void bar():
pass
# --------------------
Then you will see that an 'foo_api.h' header is generated. Look at it
at the very begining, and you will see
static PyTypeObject *__pyx_ptype_3foo_Foo;
#define PyFoo_Type (*__pyx_ptype_3foo_Foo)
static void (*bar)(void);
Then, in the API header, Cython declares the type object with a
mangled C name, and then a #define.
Then, why isn't the same approach used for the C name 'bar' for the
function pointer? Does this make sense in order to 'protect' the
Cython-generated definition to interact badly with stuff that could be
got #include'd before the point "xxxx_api.h" is #include'd ??
