Синопсис (Synopsis)

#include <systemd/sd-bus.h>

       int sd_bus_get_name_machine_id(sd_bus *bus, const char *name,
                                      sd_id128_t *machine);

Описание (Description)

sd_bus_get_name_machine_id() retrieves the D-Bus machine identity
       of the machine that the bus client identified by name is running
       on. Internally, it calls the GetMachineId method of the
       org.freedesktop.DBus.Peer interface. The D-Bus machine identity
       is a 128-bit UUID. On Linux systems running systemd, this
       corresponds to the contents of /etc/machine-id. On success, the
       machine identity is stored in machine.

Возвращаемое значение (Return value)

On success, this function returns a non-negative integer. On
       failure, it returns a negative errno-style error code.

   Errors

       -EINVAL
           An argument is invalid.

       -ENOPKG
           The bus cannot be resolved.

       -ECHILD
           The bus was created in a different process.

       -ENOMEM
