Outdated egg!
This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.
If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Predicates
uuid?
- uuid? UUIDprocedure
Is UUID a uuid?
uuid-null?
uuid-nil?
- uuid-null? UUIDprocedure
- uuid-nil? UUIDprocedure
Is UUID the nil-uuid?
uuid-compare
- uuid-compare UUID1 UUID2procedure
Returns the comparison of UUID1 and UUID2 as -1, 0, or 1.
uuid=?
- uuid=? UUID1 UUID2procedure
Are UUID1 and UUID2 equal?
uuid<?
- uuid<? UUID1 UUID2procedure
Does UUID1 order below UUID2?
uuid>?
- uuid>? UUID1 UUID2procedure
Does UUID1 order above UUID2?
uuid<=?
- uuid<=? UUID1 UUID2procedure
Does UUID1 order below or the same as UUID2?
uuid>=?
- uuid>=? UUID1 UUID2procedure
Does UUID1 order above or the same as UUID2?
Operations
uuid-clear!
- uuid-clear! UUIDprocedure
Overwrites the existing UUID with the nil-uuid.
uuid-copy
uuid-clone
- uuid-copy UUIDprocedure
- uuid-clone UUIDprocedure
Returns a copy of the UUID.
make-uuid
- (make-uuid [VARIANT [NAMESPACE NAME]]) => uuidprocedure
Returns a uuid VARIANT, or the nil-uuid when missing.
The NAMESPACE and NAME are required for V3 and V5 variants.
VARIANT is a symbol.
NAMESPACE and NAME are string.
The symbols time and random are synonyms for V1 and V4, respectively.
string->uuid
- string->uuid STRINGprocedure
Returns a new uuid from the external STRING representation.
uuid->string
- uuid->string UUIDprocedure
Returns the external string representation of UUID.
uuid-load!
- uuid-load! UUID #!optional NAMESPACEprocedure
Overwrites the existing UUID with the NAMESPACE indicated uuid. When missing "nil" is assumed.
NAMESPACE is a string.
uuid-load
- uuid-load #!optional NAMESPACEprocedure
Returns a new uuid with the NAMESPACE uuid. When missing "nil" is assumed.
NAMESPACE is a string.
uuid-import
- uuid-import STRINGprocedure
Returns a uuid from the external STRING representation.
uuid-import-binary
- uuid-import-binary STRINGprocedure
Returns a uuid from the external STRING binary representation.
uuid-import-siv
- uuid-import-siv STRINGprocedure
Returns a uuid from the external STRING single integer value representation.
uuid-export
- uuid-export UUIDprocedure
Returns the external string representation of UUID.
uuid-export-binary
- uuid-export-binary UUIDprocedure
Returns the external binary-string representation of UUID.
uuid-export-text
- uuid-export-text UUIDprocedure
Returns the external text representation of UUID.
uuid-export-siv
- uuid-export-siv UUIDprocedure
Returns the external single integer value representation of UUID.
Auxillary Procedures
uuid-version
- uuid-versionprocedure
Returns OSSP UUID Library version as an unsigned-long.
Errors
Errors generated by the OSSP UUID Library are signalled using a condition of (exn uuid), with properties message, and code.
Argument errors are signalled using error.
Usage
(require-extension uuid-ossp)
Notes
- 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-lib extension.
- Requires at least release 1.5.0 of the OSSP uuid Library.
- Installation of this egg might require manual intervention. Please see the uuid-ossp-fix.[ch] files which isolate the system header confilicts caused by the OSSP uuid.h header.
- The build uses the uuid-config tool to locate the proper include directory.
- Reed Sheridan has pointed out that the Debian system renames the library, as an existing library of the same name already exists. For example, uuid.h is ossp/uuid.h.
