Constructs a new directory_entry object.
Default constructor.
Defaulted copy constructor.
Defaulted move constructor.
4,5) Initializes the directory entry with path p and calls
to update the cached attributes. If an error occurs, the non-throwing overload leaves the directory_entry holding a default-constructed path.
[edit] 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 |
[edit] Exceptions
Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails.
1-4) Throws std::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.
- Sets a std::error_code& parameter to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur.
