NAME¶

std::filesystem::path::begin,std::filesystem::path::end - std::filesystem::path::begin,std::filesystem::path::end

Synopsis¶

iterator begin() const; (1) (since C++17)
iterator end() const; (2) (since C++17)

1) Returns an iterator to the first element of the path. If the path is empty, the
returned iterator is equal to end().
2) Returns an iterator one past the last element of the path. Dereferencing this
iterator is undefined behavior.

The sequence denoted by this pair of iterators consists of the following:

1. root-name (if any).
2. root-directory (if any).
3. Sequence of file-names, omitting any directory separators.
4. If there is a directory separator after the last file-name in the path, the last
element before the end iterator is an empty element.

Parameters¶

(none)

Return value¶

1) Iterator to the first element of the path.
2) Iterator one past the end of the path

Exceptions¶

May throw implementation-defined exceptions.

Example¶

// Run this code

#include <filesystem>
#include <iostream>
namespace fs = std::filesystem;

int main()
{
const fs::path p =
# ifdef _WIN32
"C:\\users\\abcdef\\AppData\\Local\\Temp\\";
# else
"/home/user/.config/Cppcheck/Cppcheck-GUI.conf";
# endif
std::cout << "Examining the path " << p << " through iterators gives\n";
for (auto it = p.begin(); it != p.end(); ++it)
std::cout << *it << " │ ";
std::cout << '\n';
}

Possible output:¶

--- Windows ---
Examining the path "C:\users\abcdef\AppData\Local\Temp\" through iterators gives
"C:" │ "/" │ "users" │ "abcdef" │ "AppData" │ "Local" │ "Temp" │ "" │

--- UNIX ---
Examining the path "/home/user/.config/Cppcheck/Cppcheck-GUI.conf" through iterators gives
"/" │ "home" │ "user" │ ".config" │ "Cppcheck" │ "Cppcheck-GUI.conf" │
