SafeQueue* ff_safe_queue_create

(

void

)

Create and initialize a SafeQueue instance.

Returns

Pointer to the SafeQueue

Return values

NULL	if initialization fails

ff_safe_queue_destroy()

void ff_safe_queue_destroy

(

SafeQueue *

sq

)

Destroy the SafeQueue instance.

It also frees all elements of the queue, destroys the mutex and condition variable.

ff_safe_queue_size()

size_t ff_safe_queue_size

(

SafeQueue *

sq

)

Return the length of the SafeQueue.

ff_safe_queue_push_front()

int ff_safe_queue_push_front	(	SafeQueue *	sq,
		void *	v
	)

Add data to the head of queue in the SafeQueue after locking mutex.

After adding the data, it signals the condition variable and unlocks the mutex. It increases the length of queue in the SafeQueue by one.

Parameters

sq	pointer to the SafeQueue
v	data to be added

Returns

The length of the queue

Return values

0	if the queue is not initialized
-1	if new entry cannot be created

Definition at line 85 of file safe_queue.c.

ff_safe_queue_push_back()

int ff_safe_queue_push_back	(	SafeQueue *	sq,
		void *	v
	)

Add data to the tail of queue in the SafeQueue after locking mutex.

After adding the data, it signals the condition variable and unlocks the mutex. It increases the length of queue in the SafeQueue by one.

Parameters

sq	pointer to the SafeQueue
v	data to be added

Returns

The length of the queue

Return values

0	if the queue is not initialized
-1	if new entry cannot be created

ff_safe_queue_pop_front()

void* ff_safe_queue_pop_front

(

SafeQueue *

sq

)

Remove and free first element from the queue in SafeQueue.

Before removing, it waits for the condition variable to signal and acquires the mutex. Finally, it signals the condition and unlocks the mutex. It shrinks the length of queue in the SafeQueue by one.

Parameters

sq	pointer to the SafeQueue.

Returns

The value of first element as void. If a null pointer or empty queue is passed, it returns NULL
