int aw_instance_set (void *instance)
Description
Sets the current instance.
Callback
None (returns immediately)
Notes
One instance will always be the current instance at any given moment. In multi-instance applications the current instance will constantly change in response to calls to the API and for events or callbacks. At any given time an application can change the current instance by calling this method.
All API methods operate on the current instance, which means a multi-instance application must typically call aw_instance_set before any other method in order to indicate which instance the call is for.
See Multiple instances for more information.
