- """
- refcounting
- ~~~~~~~~~~~
- Reference count annotations for C API functions. Has the same
- result as the sphinx.ext.refcounting extension but works for all
- functions regardless of the signature, and the reference counting
- information is written inline with the documentation instead of a
- separate file.
- Adds a new directive "refcounting". The directive has no content
- and one required positional parameter:: "new" or "borrow".
- Example:
- .. cfunction:: json_t *json_object(void)
- .. refcounting:: new
- <description of the json_object function>
