directory_iterator();	(1)	(filesystem TS)

Constructs a new directory iterator.

1) Constructs the end iterator.

2) Constructs a directory iterator that refers to the first directory entry of a directory identified by p. If p refers to a non-existing file or not a directory, returns the end iterator.

Exceptions

1)

noexcept specification:  

noexcept

  

2) filesystem_error if an error occurs. The exception object is constructed with p as an argument.

3)

noexcept specification:  

noexcept

  

Notes

To iterate over the current directory, construct the iterator as directory_iterator(".") instead of directory_iterator("").
