получение идентификатора машины клиента шины (Retrieve a bus client's machine identity)
Имя (Name)
sd_bus_get_name_machine_id - Retrieve a bus client's machine
identity
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
Returned errors may indicate the following problems:
-EINVAL
An argument is invalid.
-ENOPKG
The bus cannot be resolved.
-ECHILD
The bus was created in a different process.
-ENOMEM
Memory allocation failed.
Примечание (Note)
These APIs are implemented as a shared library, which can be
compiled and linked to with the libsystemd pkg-config(1) file.
