sd_id128_randomize - Generate 128-bit IDs
#include <elogind/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).
The call returns 0 on success (in which case ret is filled in), or a negative errno-style error code.
These APIs are implemented as a shared library, which can be compiled and linked to with the libelogind pkg-config(1) file.
