std::filesystem::recursive_directory_iterator::pop

From cppreference.com
 
 
 
 
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.

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

[edit] Parameters

ec - error code to store the error status to

[edit] Return value

(none)

[edit] Exceptions

The overload that does not take a std::error_code& parameter throws filesystem_error on underlying OS API errors, constructed with the OS error code as the error code argument. std::bad_alloc may be thrown if memory allocation fails. 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.
