From cppreference.com
path parent_path() const;
|
(filesystem TS) | |
Returns the path to the parent directory. Returns empty path if empty() or there's only a single element in the path (begin() == --end()).
The resulting path is constructed by appending all elements in a range [begin(), --end()) to an empty path.
Parameters
(none)
Return value
The path to the parent directory.
Exceptions
May throw implementation-defined exceptions.
Example
Run this code
#include <experimental/filesystem>
#include <iostream>
namespace fs = std::experimental::filesystem;
int main()
{
for (fs::path p : {"/var/tmp/example.txt", "/", "/var/tmp/."})
std::cout << "The parent path of " << p
<< " is " << p.parent_path() << '\n';
}
Possible output:
The parent path of "/var/tmp/example.txt" is "/var/tmp"
The parent path of "/" is ""
The parent path of "/var/tmp/." is "/var/tmp"
