Function Documentation

const char *rcl_action_server_get_action_name(const rcl_action_server_t *action_server)

Get the action name for an action server.

This function returns the action server’s internal topic name string. This function can fail, and therefore return NULL, if the:

• action server is NULL

• action server is invalid (e.g. never called init or called fini)

The returned string is only valid as long as the action server is valid. The value of the string may change if the topic name changes, and therefore copying the string is recommended if this is a concern.
