#[no_mangle]pub unsafe extern "C" fn mdata_keys_for_each(
app: *const App,
keys_h: MDataKeysHandle,
user_data: *mut c_void,

)
Iterate over the keys.
The o_each_cb
callback is invoked once for each key,
passing user data, pointer to key and key length.
The o_done_cb
callback is invoked after the iteration is done, or in case of error.
