NAME¶
sd_id128_randomize - Generate 128 bit IDsSYNOPSIS¶
#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 command may be used as 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 shared library, which can be compiled and linked to with the libsystemd-id128 pkg-config(1) file.SEE ALSO¶
