std::experimental::flex_barrier – std::experimental::flex_barrier Synopsis Defined in header <experimental/barrier> class flex_barrier; (concurrency TS) The class std::experimental::flex_barrier provides a thread-coordination mechanism that allows a set of participating threads to block until an operation is completed. Unlike std::experimental::latch, barriers are reusable; once the participating threads are released from a barrier’s synchronization point, they can reuse the same barrier….

std::experimental::filesystem::recursive_directory_iterator::recursion_pending – std::experimental::filesystem::recursive_directory_iterator::recursion_pending Synopsis bool recursion_pending() const; (filesystem TS) Returns true if the next increment will cause the directory currently referred to by *this to be iterated into.

Parameters (none) Return value true if the next increment will iterate…

std::experimental::filesystem::recursive_directory_iterator::pop – std::experimental::filesystem::recursive_directory_iterator::pop Synopsis void pop(); (filesystem TS) Moves the iterator one level up in the directory hierarchy. If the parent directory is outside directory hierarchy that is iterated on (i.e. depth() == 0), sets *this to an end directory iterator.

std::experimental::filesystem::recursive_directory_iterator::depth – std::experimental::filesystem::recursive_directory_iterator::depth Synopsis int depth() const; (filesystem TS) Returns the number of directories from the starting directory to the currently iterated directory, i.e. the current depth of the directory hierarchy.
