|
|
Reference count annotations for C API functions. Has the same |
| 6 |
|
|
result as the sphinx.ext.refcounting extension but works for all |
| 7 |
|
|
functions regardless of the signature, and the reference counting |
| 8 |
|
|
information is written inline with the documentation instead of a |
| 9 |
|
|
separate file. |
| 10 |
|
|
|
| 11 |
|
|
Adds a new directive "refcounting". The directive has no content |
| 12 |
|
|
and one required positional parameter:: "new" or "borrow". |
| 13 |
|
|
|
| 14 |
|
|
Example: |
| 15 |
|
|
|
| 16 |
|
|
.. cfunction:: json_t *json_object(void) |
| 17 |
|
|
|
| 18 |
|
|
.. refcounting:: new |
| 19 |
|
|
