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-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.
