version of this structure

set_session_id

int(* pw_client_endpoint_events::set_session_id) (void *data, uint32_t session_id)

Sets the session id of the endpoint.

On endpoints that are not session masters, this method notifies the implementation that it has been associated with a session. The implementation is obliged to set this id in the #struct pw_endpoint_info session_id field.

Parameters

endpoint	a pw_endpoint
id	the session id associated with this endpoint

Returns

0 on success -EINVAL when the session id has already been set -ENOTSUP when the endpoint is a session master

set_param

int(* pw_client_endpoint_events::set_param) (void *data, uint32_t id, uint32_t flags, const struct spa_pod *param)

Set the configurable parameter in endpoint.

Usually, param will be obtained from enum_params and then modified but it is also possible to set another spa_pod as long as its keys and types match a supported object.

Objects with property keys that are not known are ignored.

This function must be called from the main thread.

Parameters

endpoint	a #struct pw_endpoint
id	the parameter id to configure
flags	additional flags
param	the parameter to configure

Returns

0 on success -EINVAL when endpoint is NULL -ENOTSUP when there are no parameters implemented on endpoint -ENOENT the parameter is unknown

stream_set_param

int(* pw_client_endpoint_events::stream_set_param) (void *data, uint32_t stream_id, uint32_t id, uint32_t flags, const struct spa_pod *param)

Set a parameter on stream_id of endpoint.

When param is NULL, the parameter will be unset.

This function must be called from the main thread.

Parameters

endpoint	a #struct pw_endpoint
stream_id	the stream to configure
id	the parameter id to set
flags	optional flags
param	a #struct spa_pod with the parameter to set

Returns

0 on success 1 on success, the value of param might have been changed depending on flags and the final value can be found by doing stream_enum_params. -EINVAL when endpoint is NULL or invalid arguments are given -ESRCH when the type or size of a property is not correct. -ENOENT when the param id is not found

create_link

int(* pw_client_endpoint_events::create_link) (void *data, const struct spa_dict *props)
