std::experimental::filesystem::path::parent_path(3)

NAME
std::experimental::filesystem::path::parent_path - std::experimental::filesystem::path::parent_path

Synopsis
   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"
