zuuid \- UUID support class
.SH "SYNOPSIS"
.sp
.nf
//  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 \*(Aq\-\*(Aq and \*(Aq{\*(Aq \*(Aq}\*(Aq
//  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);

.SH "DESCRIPTION"
.sp
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\&.
.sp
Please add \fI@discuss\fR section in \fI\&./\&.\&./src/zuuid\&.c\fR\&.
