SYNOPSIS

//  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'.
