NAME

       sd_id128_randomize - Generate 128-bit IDs

SYNOPSIS

       #include <systemd/sd-id128.h>

       int sd_id128_randomize(sd_id128_t *ret);

DESCRIPTION

       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-id128 option may be used as a command line front-end for
       sd_id128_randomize().

RETURN VALUE

       The call returns 0 on success (in which case ret is filled in), or a negative errno-style
       error code.

NOTES

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