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-id 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 The sd_id128_randomize() interface is available as a shared library, which can be compiled and linked to with the "libsystemd" pkg-config(1) file.
