UUID * ACE_Utils::UUID_Generator::generateUUID	(	ACE_UINT16	version = 0x0001,
		u_char	variant = 0x80
	)

Format timestamp, clockseq, and nodeID into a VI UUID. For generating UUID's with thread and process ids use variant=0xc0

void ACE_Utils::UUID_Generator::generateUUID	(	UUID &	,
		ACE_UINT16	version = 0x0001,
		u_char	variant = 0x80
	)

Format timestamp, clockseq, and nodeID into an UUID of the specified version and variant. For generating UUID's with thread and process ids use variant=0xc0

void ACE_Utils::UUID_Generator::get_systemtime

[private]

the Christian calendar).

Obtain the system time in UTC as a count of 100 nanosecond intervals since 00:00:00.00, 15 October 1582 (the date of Gregorian reform to

Get the time of day, convert to 100ns ticks then add the offset.

void ACE_Utils::UUID_Generator::get_timestamp

(

UUID_time &

timestamp

)

[private]

Obtain a UUID timestamp. Compensate for the fact that the time obtained from getSystem time has a resolution less than 100ns.

void ACE_Utils::UUID_Generator::init

(

void

)

ACE_SYNCH_MUTEX * ACE_Utils::UUID_Generator::lock	(	ACE_SYNCH_MUTEX *	lock,
		bool	release_lock
	)

Set a new locking strategy and return the old one.

ACE_SYNCH_MUTEX * ACE_Utils::UUID_Generator::lock

(

void

)

The locking strategy prevents multiple generators from accessing the UUID_state at the same time. Get the locking strategy.
