SD_BUS_GET_NAME_MACHINE_ID(3)us_get_name_machine_idUS_GET_NAME_MACHINE_ID(3)
sd_bus_get_name_machine_id - Retrieve a bus client's machine identity
#include <systemd/sd-bus.h>
int sd_bus_get_name_machine_id(sd_bus *bus, const char *name,
sd_id128_t *machine);
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.
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.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
