NAME

sd_bus_get_name_machine_id - Retrieve a bus clients machine identity

SYNOPSIS

  #include <systemd/sd-bus.h>

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

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.

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.

NOTES

These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd *pkg-config*(1) file.
