WpCore
The core is the central object around which everything operates. It is essential to create a WpCore before using any other WirePlumber API.
The core object has the following responsibilities:
- it initializes the PipeWire library
- it creates a
pw_context
and allows connecting to the PipeWire server, creating a localpw_core
- it glues the PipeWire library's event loop system with GMainLoop
- it maintains a list of registered objects, which other classes use to keep objects loaded permanently into memory
- it watches the PipeWire registry and keeps track of remote and local objects that appear in the registry, making them accessible through the WpObjectManager API.

wp_core_sync
gboolean wp_core_sync (WpCore * self, GCancellable * cancellable, GAsyncReadyCallback callback, gpointer user_data)
Asks the PipeWire server to call the callback via an event.
Since methods are handled in-order and events are delivered in-order, this can be used as a barrier to ensure all previous methods and the resulting events have been handled.
