std::filesystem::path::parent_path
|
(since C++17) |
Returns the path to the parent directory.
If has_relative_path()
returns false, the result is a copy of *this
Otherwise, the result is a path whose generic format pathname is the longest prefix of the generic format pathname of *this
that produces one fewer element in its iteration.
Parameters
(none).
Return value
The path to the parent directory.
Exceptions
(none).
Example
#include <iostream>
#include <filesystem>
namespace fs = std::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"
