## Detailed Description

### template<typename T, typename A = cache_aligned_allocator<T>>
class tbb::strict_ppl::concurrent_queue< T, A >

A high-performance thread-safe non-blocking concurrent queue.

Multiple threads may each push and pop concurrently. Assignment construction is not allowed.

## Member Function Documentation

template<typename T , typename A = cache_aligned_allocator<T>>

bool tbb::strict_ppl::concurrent_queue< T, A >::try_pop | ( | T & | result) |  |
| inline

Attempt to dequeue an item from head of queue.

Does not wait for item to become available. Returns true if successful; false otherwise.
