+.TH UUID 3 "@E2FSPROGS_MONTH@ @E2FSPROGS_YEAR@" "E2fsprogs version @E2FSPROGS_VERSION@"
+.SH NAME
+uuid \- DCE compatible Universally Unique Identifier library
+.SH SYNOPSIS
+.B #include <uuid/uuid.h>
+.SH DESCRIPTION
+The UUID library is used to generate unique identifiers for objects
+that may be accessible beyond the local system. This library
+generates UUIDs compatible with those created by the Open Software
+Foundation (OSF) Distributed Computing Environment (DCE) utility
+.BR uuidgen .
+.sp
+The UUIDs generated by this library can be reasonably expected to be
+unique within a system, and unique across all systems. They could
+be used, for instance, to generate unique HTTP cookies across multiple
+web servers without communication between the servers, and without fear
+of a name clash.
+.SH "CONFORMING TO"
+OSF DCE 1.1
+.SH AUTHOR
+Theodore Y. Ts'o
+.SH AVAILABILITY
+The UUID library is part of the e2fsprogs package and is available from
+.UR http://e2fsprogs.sourceforge.net/
+http://e2fsprogs.sourceforge.net/
+.UE
+.SH "SEE ALSO"

+.SH NAME
+uuid_generate, uuid_generate_random, uuid_generate_time \- create a new unique UUID value
+.SH SYNOPSIS
+.nf
+.B #include <uuid/uuid.h>
+.sp
+.BI "void uuid_generate(uuid_t " out );
+.BI "void uuid_generate_random(uuid_t " out );
+.BI "void uuid_generate_time(uuid_t " out );
+.fi
+.SH DESCRIPTION
+The
+.B uuid_generate
+function creates a new universally unique identifier (UUID). 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 UUID's
+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.
+.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 .

+.TH UUID_TIME 3 "@E2FSPROGS_MONTH@ @E2FSPROGS_YEAR@" "E2fsprogs version @E2FSPROGS_VERSION@"
+.SH NAME
+uuid_time \- extract the time at which the UUID was created
+.SH SYNOPSIS
+.nf
+.B #include <uuid/uuid.h>
+.sp
+.BI "time_t uuid_time(uuid_t " uu ", struct timeval *" ret_tv )
+.fi
+.SH DESCRIPTION
+The
+.B uuid_time
+function extracts the time at which the supplied time-based UUID
+.I uu
+was created. Note that the UUID creation time is only encoded within
+certain types of UUIDs. This function can only reasonably expect to
+extract the creation time for UUIDs created with the
+.BR uuid_generate_time (3)
+function. It may or may not work with UUIDs created by other mechanisms.
+.SH "RETURN VALUES"
+The time at which the UUID was created, in seconds since January 1, 1970 GMT
+(the epoch), is returned (see
+.BR time "(2))."
+The time at which the UUID was created, in seconds and microseconds since
+the epoch, is also stored in the location pointed to by
+.I ret_tv
+(see
+.BR gettimeofday "(2))."

+.TH UUID_UNPARSE 3 "@E2FSPROGS_MONTH@ @E2FSPROGS_YEAR@" "E2fsprogs version @E2FSPROGS_VERSION@"
+.SH NAME
+uuid_unparse \- convert an UUID from binary representation to a string
+.SH SYNOPSIS
+.nf
+.B #include <uuid/uuid.h>
+.sp
+.BI "void uuid_unparse(uuid_t " uu ", char *" out );
+.BI "void uuid_unparse_upper(uuid_t " uu ", char *" out );
+.BI "void uuid_unparse_lower(uuid_t " uu ", char *" out );
+.fi
+.SH DESCRIPTION
+The
+.B uuid_unparse
+function converts the supplied UUID
+.I uu
+from the binary representation into a 36\-byte string (plus tailing '\\0')
+of the form 1b4e28ba\-2fa1\-11d2\-883f\-0016d3cca427 and stores this
+value in the character string pointed to by
+.IR out .
+The case of the hex digits returned by
+.B uuid_unparse
+may be upper or lower case, and is
+dependent on the system-dependent local default.
+.PP
+If the case of the
+hex digits is important then the functions
+.B uuid_unparse_upper
+and
+.B uuid_unparse_lower
+may be used.
