The devices that are installed on the system.
Sets the debug callback for the instance and associated devices. Must be set before creating devices. Depending on backend, it might only be effective if the instance was created with the right extensions.
Properties of the backend API
Backend identifier
Atomically loads the number of active references.
Atomically increment the reference count.
Atomically decrement the reference count. If refCount reaches zero, and disposeOnZero is set, the object is locked with its own mutex, and dispose is called. In most cases, the calling code should set disposeOnZero, unless it is intended to release the object to give it away. (such as at the end of a builder function)
Returns whether the refCount >= 1. This increases the refCount by 1. rcLock should be used to keep weak reference and ensures that the resource is not disposed. The operation is atomic.
