Detailed Description

PipeWire link object.

Function Documentation

◆ pw_context_create_link()

struct pw_impl_link* pw_context_create_link	(	struct pw_context *	context,
		struct pw_impl_port *	output,
		struct pw_impl_port *	input,
		struct spa_pod *	format_filter,
		struct pw_properties *	properties,
		size_t	user_data_size
	)

Make a new link between two ports.

Returns: a newly allocated link

Parameters

context	the context object
output	an output port
input	an input port
format_filter	an optional format filter
properties	extra properties
user_data_size	extra user data size

◆ pw_impl_link_add_listener()

void pw_impl_link_add_listener	(	struct pw_impl_link *	link,
		struct spa_hook *	listener,
		const struct pw_impl_link_events *	events,
		void *	data
	)

Add an event listener to link.
