| 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.
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.
The overload that does not take a std::error_code& parameter throws std::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.
