The uuid will +be generated based on high-quality randomness from +.IR /dev/urandom , +if available. If it is not available, then +.B uuid_generate +will use an alternative algorithm which uses the current time, the +local ethernet MAC address (if available), and random data generated +using a pseudo-random generator. +.sp +The +.B uuid_generate_random +function forces the use of the all-random UUID format, even if +a high-quality random number generator (i.e., +.IR /dev/urandom ) +is not available, in which case a pseudo-random +generator will be substituted. Note that the use of a pseudo-random +generator may compromise the uniqueness of UUIDs +generated in this fashion. +.sp +The +.B uuid_generate_time +function forces the use of the alternative algorithm which uses the +current time and the local ethernet MAC address (if available). +This algorithm used to be the default one used to generate UUID, but +because of the use of the ethernet MAC address, it can leak +information about when and where the UUID was generated. This can cause +privacy problems in some applications, so the +.B uuid_generate +function only uses this algorithm if a high-quality source of +randomness is not available. To guarantee uniqueness of UUIDs generated +by concurrently running processes, the uuid library uses global +clock state counter (if the process has permissions to gain exclusive access +to this file) and/or the +.B uuidd +daemon, if it is running already or can be spawned by the process (if +installed and the process has enough permissions to run it). If neither of +these two synchronization mechanisms can be used, it is theoretically possible +that two concurrently running processes obtain the same UUID(s). To tell +whether the UUID has been generated in a safe manner, use +.BR uuid_generate_time_safe . +.sp +The +.B uuid_generate_time_safe +is similar to +.BR uuid_generate_time , +except that it returns a value which denotes whether any of the synchronization +mechanisms (see above) has been used. +.sp +The UUID is 16 bytes (128 bits) long, which gives approximately 3.4x10^38 +unique values (there are approximately 10^80 elementary particles in +the universe according to Carl Sagan's +.IR Cosmos ). +The new UUID can reasonably be considered unique among all UUIDs created +on the local system, and among UUIDs created on other systems in the past +and in the future. +.SH RETURN VALUE +The newly created UUID is returned in the memory location pointed to by +.IR out . +.B uuid_generate_time_safe +returns zero if the UUID has been generated in a safe manner, \-1 otherwise. +.SH "CONFORMING TO" +OSF DCE 1.1 +.SH AUTHOR +Theodore Y.\& Ts'o +.SH AVAILABILITY +.B libuuid +is part of the util-linux package since version 2.15.1 and is available from +ftp://ftp.kernel.org/pub/linux/utils/util-linux/. +.SH "SEE ALSO" +.BR uuid (3), +.BR uuidgen (1), +.BR uuidd (8), +.BR uuid_clear (3), +.BR uuid_compare (3), +.BR uuid_copy (3), +.BR uuid_is_null (3), +.BR uuid_parse (3), +.BR uuid_time (3), +.BR uuid_unparse (3) diff --git a/libblkid/libuuid/man/uuid_is_null.3 b/libblkid/libuuid/man/uuid_is_null.3 new file mode 100644 index 000000000..86a7a50fe --- /dev/null +++ b/libblkid/libuuid/man/uuid_is_null.3 @@ -0,0 +1,64 @@ +.\" Copyright 1999 Andreas Dilger (adilger@enel.ucalgary.ca) +.\" +.\" %Begin-Header% +.\" Redistribution and use in source and binary forms, with or without +.\" modification, are permitted provided that the following conditions +.\" are met: +.\" 1.
