module-specific data with a specific container object.
A registry is associated with a struct tag name.
The exported API is best used via the wrapper macros:
- register_TAG_data(TAG)
Get a new key for the container type TAG.
- register_TAG_data_with_cleanup(TAG, SAVE, FREE)
Get a new key for the container type TAG.
SAVE and FREE are defined as void (*) (struct TAG *, void *)
When the container is destroyed, first all registered SAVE
functions are called.
Then all FREE functions are called.
Either or both may be NULL.
- clear_TAG_data(TAG, OBJECT)
Clear all the data associated with OBJECT. Should be called by the
container implementation when a container object is destroyed.
- set_TAG_data(TAG, OBJECT, KEY, DATA)
Set the data on an object.
- TAG_data(TAG, OBJECT, KEY)
Fetch the data for an object; returns NULL if it has not been set.
