Field Documentation

◆ add_listener

int(* pw_port_methods::add_listener) (void *object, struct spa_hook *listener, const struct pw_port_events *events, void *data)

◆ enum_params

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

Enumerate port parameters.

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

Parameters
seqa sequence number returned in the reply
idthe parameter id to enumerate
startthe start index or 0 for the first param
numthe maximum number of params to retrieve
filtera param filter or NULL

◆ subscribe_params

int(* pw_port_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
idsan array of param ids
n_idsthe number of ids in ids
