std::filesystem::path::parent_path
From cppreference.com
path parent_path() const;
|
(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, or a copy of *this if not has_relative_path().
Exceptions
May throw implementation-defined exceptions.
Example
Run this code
#include <filesystem>
#include <iostream>
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"
