std::filesy...parent_path(3) C++ Standard Libary std::filesy...parent_path(3) NAME std::filesystem::path::parent_path - std::filesystem::path::parent_path Synopsis 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 it- eration. Parameters (none) Return value The path to the parent directory, or a copy of *this if not has_rel- ative_path(). Exceptions May throw implementation-defined exceptions. Example // Run this code #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" See also root_name returns the root-name of the path, if present (public member function) root_directory returns the root directory of the path, if present (public member function) root_path returns the root path of the path, if present (public member function) http://cppreference.com 2022.07.31 std::filesy...parent_path(3)
