Имя (Name)

sd_bus_list_names - Retrieve information about registered names
       on a bus

---

Синопсис (Synopsis)

#include <systemd/sd-bus.h>

       int sd_bus_list_names(sd_bus *bus, char ***acquired,
                             char ***activatable);

---

Описание (Description)

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.
