std::filesystem::path::parent_path - cppreference.com (original) (raw)

| 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.

[edit] Parameters

(none)

[edit] Return value

The path to the parent directory, or a copy of *this if not has_relative_path().

[edit] Exceptions

May throw implementation-defined exceptions.

[edit] Example

#include #include 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"
