(6) (since C++17)

Contructs new recursive directory iterator.

1) Default constructor. Constructs an end iterator.
2) Copy constructor.
3) Move constructor.
4-6) Constructs a iterator that refers to the first entry in the directory that p resolves to.

[edit] Parameters

[edit] Exceptions

The overload that does not take a std::error_code& parameter throws filesystem::filesystem_error on underlying OS API errors, constructed with p as the first path argument and the OS error code as the error code argument. 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.

[edit] 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.

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
