std::filesystem::directory_iterator::operator++, std::filesystem::directory_iterator::increment

directory_iterator& operator++();
directory_iterator& increment( std::error_code& ec );

Advances the iterator to the next entry. Invalidates all copies of the previous value of *this.

Parameters

Return value

*this.

Exceptions

The overload that does not take a std::error_code& parameter throws filesystem::filesystem_error on underlying OS API errors, constructed with 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.
