NAME

std::filesystem::recursive_directory_iterator::recursive_directory_iterator - std::filesystem::recursive_directory_iterator::recursive_directory_iterator

Synopsis


recursive_directory_iterator() noexcept; (1) (since C++17)
recursive_directory_iterator( const recursive_directory_iterator& (2) (since C++17)
rhs );
recursive_directory_iterator( recursive_directory_iterator&& rhs ) (3) (since C++17)
noexcept;
explicit recursive_directory_iterator( const (4) (since C++17)
std::filesystem::path& p );
recursive_directory_iterator(


const std::filesystem::path& p, (4) (since C++17)


std::filesystem::directory_options options );
recursive_directory_iterator(


const std::filesystem::path& p, (5) (since C++17)
std::filesystem::directory_options options,


std::error_code& ec );
recursive_directory_iterator( const std::filesystem::path& p, (6) (since C++17)
std::error_code& ec );


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.

Parameters

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.

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.
