◆ version

uint32_t pw_endpoint_link_methods::version

version of this structure

int(* pw_endpoint_link_methods::add_listener) (void *object, struct spa_hook *listener, const struct pw_endpoint_link_events *events, void *data)

int(* pw_endpoint_link_methods::subscribe_params) (void *object, uint32_t *ids, uint32_t n_ids)

Subscribe to parameter changes.

Automatically emit param events for the given ids when they are changed.

Parameters

ids	an array of param ids
n_ids	the number of ids in ids

int(* pw_endpoint_link_methods::enum_params) (void *object, int seq, uint32_t id, uint32_t start, uint32_t num, const struct spa_pod *filter)

Enumerate link parameters.

Start enumeration of link parameters. For each param, a param event will be emitted.

Parameters

seq	a sequence number returned in the reply
id	the parameter id to enumerate
start	the start index or 0 for the first param
num	the maximum number of params to retrieve
filter	a param filter or NULL

int(* pw_endpoint_link_methods::set_param) (void *object, uint32_t id, uint32_t flags, const struct spa_pod *param)

Set a parameter on the link.

Parameters

int(* pw_endpoint_link_methods::request_state) (void *object, enum pw_endpoint_link_state state)
