CZMQ Manual - CZMQ/2.2.1
Name
zuuid - UUID support class
Synopsis
// Constructor
CZMQ_EXPORT zuuid_t *
zuuid_new (void);
// Destructor
CZMQ_EXPORT void
zuuid_destroy (zuuid_t **self_p);
// Return UUID binary data
CZMQ_EXPORT byte *
zuuid_data (zuuid_t *self);
// Return UUID binary size
CZMQ_EXPORT size_t
zuuid_size (zuuid_t *self);
// Returns UUID as string
CZMQ_EXPORT char *
zuuid_str (zuuid_t *self);
// Set UUID to new supplied value
CZMQ_EXPORT void
zuuid_set (zuuid_t *self, byte *source);
// Store UUID blob in target array
CZMQ_EXPORT void
zuuid_export (zuuid_t *self, byte *target);
// Check if UUID is same as supplied value
CZMQ_EXPORT bool
zuuid_eq (zuuid_t *self, byte *compare);
// Check if UUID is different from supplied value
CZMQ_EXPORT bool
zuuid_neq (zuuid_t *self, byte *compare);
// Make copy of UUID object
CZMQ_EXPORT zuuid_t *
zuuid_dup (zuuid_t *self);
// Self test of this class
CZMQ_EXPORT int
zuuid_test (bool verbose);
Description
The zuuid class generates UUIDs and provides methods for working with them. If you build CZMQ with libuuid, on Unix/Linux, it will use that library. On Windows it will use UuidCreate(). Otherwise it will use a random number generator to produce convincing imitations of uuids.
Example
From zuuid_test method
// Simple create/destroy test
zuuid_t *uuid = zuuid_new ();
assert (uuid);
assert (zuuid_size (uuid) == 16);
assert (strlen (zuuid_str (uuid)) == 32);
zuuid_t *copy = zuuid_dup (uuid);
assert (streq (zuuid_str (uuid), zuuid_str (copy)));
zuuid_destroy (&uuid); zuuid_destroy (©);
