7 uuidd \- UUID generation daemon
45 daemon is used by the UUID library to generate
46 universally unique identifiers (UUIDs), especially time-based UUID's
47 in a secure and guaranteed-unique fashion, even in the face of large
48 numbers of threads trying to grab UUID's running on different CPU's.
54 in debugging mode. This prevents uuidd from running as a daemon.
57 If a currently uuidd daemon is running, kill it.
60 When issuing a test request to a running uuidd, request a bulk response
66 Specify the pathname where the pid file should be written. By default,
67 the pid file is written to /var/lib/libuuid/uuidd.pid.
70 Specify the pathname used for the unix-domain socket used by uuidd. By
71 default, the pathname used is /var/lib/libuuid/request. This is primarily
72 for debugging purposes, since the pathname is hard-coded in the libuuid
76 Test uuidd by trying to connect to a running uuidd daemon and
77 request it to return a random-based UUID.
80 Test uuidd by trying to connect to a running uuidd daemon and
81 request it to return a time-based UUID.
84 Specify a timeout for uuidd. If specified, then uuidd will exit after
86 seconds of inactivity.
