sd_bus_list_names - Retrieve information about registered names on a bus

sd_bus_list_names() retrieves information about the registered names on a bus. If acquired is not NULL, this function calls org.freedesktop.DBus.ListNames[1] to retrieve the list of currently-owned names on the bus. If acquired is not NULL, the function calls org.freedesktop.DBus.ListActivableNames[2] to retrieve the list of all names on the bus that can be activated. Note that ownership of the arrays returned by sd_bus_list_names() in acquired and activatable is transferred to the caller and hence, the caller is responsible for freeing these arrays and their contents.

sd_bus_list_names() was added in version 221.
