void pop();	(1)	(since C++17)
void pop( std::error_code& ec );	(2)	(since C++17)

Moves the iterator one level up in the directory hierarchy. Invalidates all copies of the previous value of *this.

If the parent directory is outside directory hierarchy that is iterated on (i.e. depth() == 0), sets *this to an end directory iterator.

Parameters

ec

-

error code to store the error status to

Return value

(none)

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.
