ZUUID(3) CZMQ Manual ZUUID(3)

zuuid - Class for UUID support class

//  This is a stable class, and may not change except for emergencies. It
//  is provided in stable builds.
//  Create a new UUID object.
CZMQ_EXPORT zuuid_t *
    zuuid_new (void);
// Create UUID object from supplied ZUUID_LEN-octet value. CZMQ_EXPORT zuuid_t * zuuid_new_from (const byte *source);
// Destroy a specified UUID object. CZMQ_EXPORT void zuuid_destroy (zuuid_t **self_p);
// Set UUID to new supplied ZUUID_LEN-octet value. CZMQ_EXPORT void zuuid_set (zuuid_t *self, const byte *source);
// Set UUID to new supplied string value skipping '-' and '{' '}' // optional delimiters. Return 0 if OK, else returns -1. CZMQ_EXPORT int zuuid_set_str (zuuid_t *self, const char *source);
// Return UUID binary data. CZMQ_EXPORT const 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 const char * zuuid_str (zuuid_t *self);
// Return UUID in the canonical string format: 8-4-4-4-12, in lower // case. Caller does not modify or free returned value. See // http://en.wikipedia.org/wiki/Universally_unique_identifier CZMQ_EXPORT const char * zuuid_str_canonical (zuuid_t *self);
// 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, const byte *compare);
// Check if UUID is different from supplied value CZMQ_EXPORT bool zuuid_neq (zuuid_t *self, const byte *compare);
// Make copy of UUID object; if uuid is null, or memory was exhausted, // returns null. CZMQ_EXPORT zuuid_t * zuuid_dup (zuuid_t *self);
// Self test of this class. CZMQ_EXPORT void zuuid_test (bool verbose);
Please add '@interface' section in './../src/zuuid.c'.

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.
Please add @discuss section in ./../src/zuuid.c.

From zuuid_test method.
//  Simple create/destroy test
assert (ZUUID_LEN == 16);
assert (ZUUID_STR_LEN == 32);
zuuid_t *uuid = zuuid_new (); assert (uuid); assert (zuuid_size (uuid) == ZUUID_LEN); assert (strlen (zuuid_str (uuid)) == ZUUID_STR_LEN); zuuid_t *copy = zuuid_dup (uuid); assert (streq (zuuid_str (uuid), zuuid_str (copy)));
