Include dependency graph for uuid.h:

This graph shows which files directly or indirectly include this file:

Macros
#define	UUID_NODE_LEN (6U)
	Size of the node identifier in bytes.

#define	UUID_STR_LEN (36U)
	Size of a string UUID without null character.

Functions
void	uuid_v3 (uuid_t uuid, const uuid_t ns, const uint8_t *name, size_t len)
	Generate a version 3(md5 based) UUID from a namespace and a byte array.

void	uuid_v4 (uuid_t *uuid)
	Generate a version 4(Full random) UUID.

void	uuid_v5 (uuid_t uuid, const uuid_t ns, const uint8_t *name, size_t len)
	Generate a version 5(sha1 based) UUID from a namespace and a byte array.

static unsigned	uuid_version (const uuid_t *uuid)
	Retrieve the type number of a UUID.

static bool	uuid_equal (const uuid_t uuid1, const uuid_t uuid2)
	Compare two UUID's.

void	uuid_to_string (const uuid_t uuid, char str)
	Generate an UUID string from an UUID structure.

int	uuid_from_string (uuid_t uuid, const char str)
	Populate an UUID structure from an UUID string.

UUID version identifiers
#define	UUID_V1 (0x01)
	Type 1 UUID - timestamp based

#define	UUID_V2 (0x02)
	Type 2 UUID - DCE Security version.

#define	UUID_V3 (0x03)
	Type 3 UUID - Name based with MD5

#define	UUID_V4 (0x04)
	Type 4 UUID - Random generated

#define	UUID_V5 (0x05)
	Type 5 UUID - Name based with SHA1.

Version part of the time_hi field
#define	UUID_VERSION_MASK (0xF000)
