NAME         top

       sd_id128_randomize - Generate 128-bit IDs

SYNOPSIS         top

       #include <systemd/sd-id128.h>

       int sd_id128_randomize(sd_id128_t *ret);

DESCRIPTION         top

       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

       Note that sd_id128_randomize() always returns a UUID
       v4-compatible ID.

       For more information about the "sd_id128_t" type, see

       systemd-id128(1)'s new command may be used as a command line
       front-end for sd_id128_randomize().

RETURN VALUE         top

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

NOTES         top

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