成员函数说明

addReleaseCallback()

vrpn_bool addReleaseCallback	(	void *	userdata,
		int(*	)(void *) )

These callbacks are triggered when ANY peer releases the mutex.

addRequestDeniedCallback()

vrpn_bool addRequestDeniedCallback	(	void *	userdata,
		int(*	)(void *) )

These callbacks are triggered when OUR request is denied.

addRequestGrantedCallback()

vrpn_bool addRequestGrantedCallback	(	void *	userdata,
		int(*	)(void *) )

These callbacks are triggered when OUR request is granted.

addTakeCallback()

vrpn_bool addTakeCallback	(	void *	userdata,
		int(*	)(void *) )

These callbacks are triggered when ANY peer gets the mutex.

isAvailable()

vrpn_bool isAvailable

(

void

)

const

True from when release() is called or we receive a release message from another process until request() is called or we grant the lock to another process in response to its request message.

isHeldLocally()

vrpn_bool isHeldLocally

(

void

)

const

True from when RequestGranted callbacks are triggered until release() is called.

isHeldRemotely()

vrpn_bool isHeldRemotely

(

void

)

const

True from when we grant the lock to another process in response to its request message until we receive a release message from another process.

release()

void release

(

void

)

Release the distributed lock. Does nothing if !isHeldLocally() and there isn't a request pending.

request()

void request

(

void

)

Request the distributed lock. Does not request the lock if !isAvailable(), instead automatically triggering DeniedCallbacks.
