directory_iterator& operator++(); | (1) | (since C++17) |
directory_iterator& increment( std::error_code& ec ); | (2) | (since C++17) |
Advances the iterator to the next entry. Invalidates all copies of the previous value of *this.

Return value
*this
Exceptions
Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails.
1) Throws
std::filesystem::filesystem_error on underlying OS API errors, constructed with the OS error code as the error code argument.
2) 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.Example
