std::experimental::flex_barrier

explicit flex_barrier( std::ptrdiff_t num_threads );

(concurrency TS)
template< class F >
flex_barrier( std::ptrdiff_t num_threads, F completion );
(2)
(concurrency TS)
flex_barrier( std::ptrdiff_t num_threads, F completion );
flex_barrier( const flex_barrier & ) = delete;
(3)
(concurrency TS)
1) Has the same effect as flex_barrier(num_threads, c), where
c is a Callable object whose invocation returns -1 and has no side effects.2) Constructs a
flex_barrier for num_threads participating threads, using completion for the completion phase. The set of participating threads is the first num_threads threads to arrive at the synchronization point.3) Copy constructor is deleted;
flex_barrier is not copyable.[edit] Parameters
num_threads
-
the number of participating threads for the
flex_barrier; must be non-negative
completion
-
a function object controlling the completion phase; must be Callable with no arguments and return type std::ptrdiff_t , and when invoked, must return a value no less than -1 and must not throw an exception
Type requirements
-
F must meet the requirements of CopyConstructible.
[edit] Notes
If num_threads is zero, the set of participating threads is empty, and flex_barrier can only be destroyed.
