SD_ID128_RANDOMIZE(3) sd_id128_randomize SD_ID128_RANDOMIZE(3)
sd_id128_randomize - Generate 128-bit IDs
#include <systemd/sd-id128.h>
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-id128 option may be used as a 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 a shared library,
which can be compiled and linked to with the
"libsystemd" pkg-config(1) file.
