More complicated concept is ValueManager.
|
|
It is like ValueMutex, but user can subscribe to value updates.
|
|
|
|
First of all you can use value and pubsub part as showing above:
|
|
aquire/release mutex, read value, subscribe/unsubscribe pubsub.
|
|
There are two specific methods for ValueManager: write_managed, commit_managed
