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
3) Copy constructor is deleted;
flex_barrier is not copyable.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 |
| Type requirements | ||
-
F must meet the requirements of CopyConstructible

Notes
If num_threads is zero, the set of participating threads is empty, and flex_barrier can only be destroyed.
