NAME¶
sd_bus_get_name_machine_id - Retrieve a bus client's machine identity
SYNOPSIS¶
#include <elogind/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 elogind, 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.
