OSF DCE 1.1 UUID

Documentation

Wrapper for uuid/uuid.h procedures on macOS X, and Linux.

Operations

make-uuid

[procedure] (make-uuid [METHOD]) -> uuid

Returns a new uuid, as uuid-generate, or a null-uuid as the default.

uuid-generate

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

Returns a new uuid.

METHOD

(or false symbol) ; the UUID Version

'v1, 'V1, or 'time

DCE Version 4 (random) algorithm.

'v4, 'V4, or 'random

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 condition.

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.

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-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

(or false symbol) ; 'upper, 'lower, or #f. Default is #f.

An invalid CASE is an error condition.

Predicates

uuid?

[procedure] (uuid? UUID) -> boolean

Is UUID a uuid?

uuid-null?

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

Is UUID the null uuid?

uuid-compare

[procedure] (uuid-compare UUID1 UUID2) -> fixnum

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

uuid=?

uuid<?

uuid>?

uuid<=?

uuid>=?

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

uuid-compare wrappers.

uuid-hash

[procedure] (uuid-hash UUID [BOUND [RANDOMIZATION]]) -> fixnum

Returns a hash of the UUID, modulo the BOUND, & the RANDOMIZATION.

A srfi-69 compatible hash function.

Version & Variant

uuid-version : {{(or false fixnum)

uuid-variant : {{(or false symbol)

Note the variant name misuse will be remedied.

uuid-version?

[procedure] (uuid-version? OBJ) -> boolean

Is the OBJ a uuid-version, #f or [0..15]?

uuid-version->variant

[procedure] (uuid-version->variant OBJ) -> variant

uuid-variant->version

[procedure] (uuid-variant->version VAR) -> uuid-version

uuid-variant

[procedure] (uuid-variant UUID) -> uuid-variant

check-uuid

[procedure] (uuid-print UUID [PORT]) -> boolean

check-uuid

error-uuid

[procedure] (check-uuid LOC OBJ [ARGNAM]) -> uuid
[procedure] (error-uuid LOC OBJ [ARGNAM])) -> void

check-uuid

error-uuid

[procedure] (check-uuid-version LOC OBJ [ARGNAM])) -> uuid-version
[procedure] (error-uuid-version LOC * [ARGNAM])) -> void

Usage

(import uuid-lib)

Notes

• All UUIDs are Variant 1.
• The uuid?, uuid-null?, uuid-compare, uuid=?, uuid<?, uuid>?, uuid<=?, uuid>=?, make-uuid, uuid-copy, uuid-clear!, string->uuid, uuid->string share the same signature as the corresponding routines in the uuid-ossp extension.

Requirements

record-variants

test test-utils
