◆ 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
sqpointer to the SafeQueue
vdata to be added
Returns
The length of the queue
Return values
0if the queue is not initialized
-1if 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
sqpointer to the SafeQueue
vdata to be added
Returns
The length of the queue
Return values
0if the queue is not initialized
-1if 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
sqpointer to the SafeQueue.
Returns
The value of first element as void. If a null pointer or empty queue is passed, it returns NULL
