14 sd_id128_randomize() generates a new randomized 128-bit ID and returns
15 it in ret. Every invocation returns a new randomly generated ID. This
16 uses the /dev/urandom kernel random number generator.
17
18 Note that sd_id128_randomize() always returns a UUID v4-compatible ID.

22 systemd-id128(1)'s new command may be used as a command line front-end
23 for sd_id128_randomize().
24
26 The call returns 0 on success (in which case ret is filled in), or a
27 negative errno-style error code.

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