Function rcl_client_request_publisher_get_actual_qos

Function Documentation

const rmw_qos_profile_t *rcl_client_request_publisher_get_actual_qos(const rcl_client_t *client)

Get the actual qos settings of the client’s request publisher.

Used to get the actual qos settings of the client’s request publisher. The actual configuration applied when using RMW_*_SYSTEM_DEFAULT can only be resolved after the creation of the client, and it depends on the underlying rmw implementation. If the underlying setting in use can’t be represented in ROS terms, it will be set to RMW_*_UNKNOWN. The returned struct is only valid as long as the rcl_client_t is valid.
