Constructs an end iterator. 2) Copy constructor. 3) Move constructor. 4-6) Constructs a iterator that refers to the first entry in the di- rectory that p resolves to. This section is incomplete Reason: errors Parameters This section is incomplete Exceptions The overload that does not take a std::error_code& parameter throws filesystem::filesystem_error on underlying OS API errors, con- structed with p as the first path argument and the OS error code as the error code argu- ment. The overload taking a std::error_code& parameter sets it to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur. Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails. Notes Recursive directory iterators do not follow directory symlinks by default. To enable this behavior, specify directory_options::follow_directory_symlink among the options option set. Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards.
