__gnu_parallel::_RestrictedBoundedConcurrentQueue3cxx
Double-ended queue of bounded size, allowing lock-free atomic access. push_front() and pop_front() must not be called concurrently to each other, while pop_back() can be called concurrently at all times. empty(), size(), and top() are intentionally not provided. calling them would not make sense in a concurrent setting.
Usage
#include <queue.h>
Public Member Functions
_RestrictedBoundedConcurrentQueue (_SequenceIndex __max_size)
Constructor. Not to be called concurrent, of course. ~_RestrictedBoundedConcurrentQueue ()
Destructor. Not to be called concurrent, of course. bool pop_back (_Tp &__t)
Pops one element from the queue at the front end. Must not be called concurrently with pop_front(). bool pop_front (_Tp &__t)
Pops one element from the queue at the front end. Must not be called concurrently with pop_front(). void push_front (const _Tp &__t)
Pushes one element into the queue at the front end. Must not be called concurrently with pop_front().
