uuid?

[procedure] (uuid? UUID) => boolean

[procedure] (uuid-null? UUID) => boolean

Is UUID the null uuid?

uuid-compare

[procedure] (uuid-compare UUID1 UUID2) => integer

Returns -1, 0. or 1 for the comaprison of UUID1 and UUID2.

uuid=?

[procedure] (uuid=? UUID1 UUID2) => boolean

Are UUID1 and UUID2 equal?

uuid<?

[procedure] (uuid<? UUID1 UUID2) => boolean

Does UUID1 order below UUID2?

uuid>?

[procedure] (uuid>? UUID1 UUID2) => boolean

Does UUID1 order above UUID2?

uuid<=?

[procedure] (uuid<=? UUID1 UUID2) => boolean

Does UUID1 order below or the same as UUID2?

uuid>=?

[procedure] (uuid>=? UUID1 UUID2) => boolean

Does UUID1 order above or the same as UUID2?

Operations

uuid-clear!

[procedure] (uuid-clear! UUID) => uuid

Returns the UUID set to the null-uuid.

uuid-copy

[procedure] (uuid-copy UUID) => uuid

Returns a copy of the UUID.

make-uuid

[procedure] (make-uuid [VARIANT]) => uuid

Returns a new uuid.

VARIANT is:

'V1 or 'time
DCE Version 1 (MAC address) algorithm.
'V4 or 'random
DCE Version 4 (random) algorithm.
#f
The null-uuid. The default.

An invalid MODE is an error condtion.

string->uuid

[procedure] (string->uuid UUID-STRING) => uuid

Returns a new uuid from the external string representation UUID-STRING.

uuid->string

[procedure] (uuid->string UUID) => string

Returns the external string representation of UUID.

uuid-generate

[procedure] (uuid-generate [METHOD]) => uuid

Returns a new uuid.

METHOD is:

'random
DCE Version 4 (random) algorithm.
'time
DCE Version 1 (MAC address) algorithm.
#f
DCE V4 if a high-quality random device available, otherwise DCE V1. The default.

An invalid METHOD is an error condtion.

uuid-parse

[procedure] (uuid-parse UUID-TEXT) => uuid

Returns a new uuid from the external string representation UUID-TEXT.

uuid-unparse

[procedure] (uuid-unparse UUID [CASE]) => string

Returns the external string representation of UUID.

CASE is #f (the system dependent local default), 'upper, or 'lower. Default is #f.

An invalid CASE is an error condtion.
