Still missing a proper review of the linked objects, but at least this now explains why those two are split.

/** \page page_api API Documentation
|
|
|
|
The API consists of two parts:
|
|
|
|
- The \ref page_core_api to access a PipeWire instance. This API is used
|
|
by all clients that need to communicate with the \ref page_daemon and provides
|
|
the necessary structs to interface with the daemon.
|
|
- The \ref page_implementation_api and tools to build new objects and modules.
|
|
This API is primarily used by the \ref page_daemon itself but also by the
|
|
\ref page_session_manager and modules/extensions that need to build objects in
|
|
the graph.
|
|
|
|
The APIs work through proxy objects, so that calling a method on an object
|
|
invokes that same method on the remote side. Marshalling and de-marshalling is
|
|
handled transparently by the \ref page_module_protocol_native.
|
|
The below graph illustrates this approach:
|
|
|
|
@dot
|
|
digraph API {
|
|
compound=true;
|
|
node [shape="box"];
|
|
rankdir="RL";
|
|
|
|
subgraph cluster_daemon {
|
|
rankdir="TB";
|
|
label="PipeWire daemon";
|
|
style="dashed";
|
|
|
|
impl_core [label="Core Impl. Object"];
|
|
impl_device [label="Device Impl. Object"];
|
|
impl_node [label="Node Impl. Object"];
|
|
}
|
|
|
|
subgraph cluster_client {
|
|
rankdir="TB";
|
|
label="PipeWire client";
|
|
style="dashed";
|
|
|
|
obj_core [label="Core Object"];
|
|
obj_device [label="Device Object"];
|
|
obj_node [label="Node Object"];
|
|
}
|
|
|
|
obj_core -> impl_core;
|
|
obj_device -> impl_device;
|
|
obj_node -> impl_node;
|
|
|
|
}
|
|
@enddot
|
|
|
|
It is common for clients to use both the Core API and the Implementation API
|
|
and both APIs are provided by the same library.
|
|
|
|
\section page_core_api Core API
|
|
|
|
The Core API serves to access a PipeWire instance. This API is used by all
|
|
clients to communicate with the \ref page_daemon. It consists of the
|
|
following object-specific APIs:
|
|
|
|
- \ref pw_core
|
|
- \ref pw_context
|
|
- \ref pw_global
|
|
- \ref pw_client
|
|
- \ref pw_resource
|
|
- \ref pw_node
|
|
- \ref pw_port
|
|
- \ref pw_link
|
|
|
|
If you are familiar with Wayland implementation, the Core API is
|
|
roughly equivalent to libwayland-client.
|
|
|
|
\section page_implementation_api Implementation API
|
|
|
|
The implementation API provides the tools to build new objects and
|
|
modules. It consists of the following object-specific APIs:
|
|
|
|
- \ref pw_impl_core
|
|
- \ref pw_impl_client
|
|
- \ref pw_impl_device
|
|
- \ref pw_impl_factory
|
|
- \ref pw_impl_link
|
|
- \ref pw_impl_metadata
|
|
- \ref pw_impl_module
|
|
- \ref pw_impl_node
|
|
- \ref pw_impl_port
|
|
- \ref pw_control
|
|
- \ref pw_global
|
|
- \ref pw_resource
|
|
- \ref pw_work_queue
|
|
|
|
If you are familiar with Wayland implementation, the Implementation API is
|
|
roughly equivalent to libwayland-server.
