As you may know, there is a little document in WebKit. So, it looks EFL port has one of best documentation among other ports.
In my opinion, we decide to follow EFL coding style for public APIs because those are used by EFL application. If NULL is C style and EFL style,
I think we can use NULL instead of 0. But, if specific bus only start to use it, I think this can make confusion in other bug. So, if we decide to
use NULL for API documentation, I think it is better to change this at once.

Title : Using 0 or NULL in public C headers documentation ?
At the moment, we using not consistent in the usage of NULL or 0 in the documentation of our public C headers.
The best practice is not currently documented by:
However, Gyuyoung is telling me there is an "unspoken" rule for WebKit-EFL port that we should use 0.
I personally disagree and I think we should *always* use NULL in our public C headers.
While 0 is advised for null pointers in C++, it is not for C (http://lwn.net/Articles/93574/).
If you look at the EVAS documentation, it is also using NULL in its documentation, not 0.
What do other WebKit EFL developers think?
We need to agree first, then document it on the coding style page and patch the code accordingly.

* @param o the view object to get Ewk_Settings
* @return the Ewk_Settings of this view or @c NULL on failure
EAPI Ewk_Settings *ewk_view_settings_get(const Evas_Object *o);
