sd_id128_randomize — Generate 128 bit IDs

| int sd_id128_randomize( | sd_id128_t* ret ); | 
sd_id128_randomize()
                generates a new randomized 128 bit ID and returns it
                in ret. Every invocation
                returns a new randomly generated ID. This uses the
                /dev/urandom kernel random number
                generator.
Note that
                sd_id128_randomize() always returns
                a UUID v4 compatible
                ID.
For more information about the
                sd_id128_t type see
                sd-id128(3).
journalctl(1)'s
                --new-id command may be used as
                command line front-end for
                sd_id128_randomize().
The call returns 0 on success (in which
                case ret is filled in), or a
                negative errno-style error code.
The sd_id128_randomize() interface
                is available as shared library, which can be compiled
                and linked to with the
                libsystemd-id128
                pkg-config(1)
                file.
