std::filesystem::directory_entry::directory_entry (3) Linux Manual Page

std::filesystem::directory_entry::directory_entry – std::filesystem::directory_entry::directory_entry

Synopsis

directory_entry() noexcept = default;
(1)(since C++ 17)

    directory_entry(const directory_entry &) = default;
(2)(since C++ 17)

    directory_entry(directory_entry &&) noexcept = default;
(3)(since C++ 17)

    explicit directory_entry(const std::filesystem::path &p);
(4)(since C++ 17)

    directory_entry(const std::filesystem::path &p, std::error_code &ec);

Constructs a new directory_entry object.
1) Default constructor.
2) Defaulted copy constructor.
3) Defaulted move constructor.
4) Initializes the directory entry with path p and calls refresh to update the cached attributes. If an error occurs, the non-throwing overload leaves the directory_entry holding a default-constructed path.

Parameters

p – path to the filesystem object to which the directory entry will refer
ec – out-parameter for error reporting in the non-throwing overload

Exceptions

The overload that does not take a std::error_code& parameter throws 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.
