Returns the internal pathname in native pathname format, converted to specific string type. Conversion, if any, is specified in todo.
1) All memory allocations are performed by
a.2) The encoding in the case of
u8string() is always UTF-8.Parameters
(none)
Return value
The internal pathname in native pathname format, converted to specified string type.
Exceptions
May throw implementation-defined exceptions.
Example
Run this code
#include <cstdio> #include <clocale> #include <fstream> #include <iostream> #include <experimental/filesystem> namespace fs = std::experimental::filesystem; int main() { std::setlocale(LC_ALL, "en_US.utf8"); std::locale::global(std::locale("en_US.utf8")); fs::path p = fs::u8path(u8"要らない.txt"); // native string representation can be used with OS APIs std::ofstream(p) << "File contents"; // this uses operator string() if(std::FILE* f = std::fopen(p.c_str(), "r")) { int ch; while((ch=fgetc(f))!= EOF) putchar(ch); std::fclose(f); } // multibyte and wide representation can be used for output std::cout.imbue(std::locale()); std::cout << "\nFile name in narrow multibyte encoding: " << p.string() << '\n'; std::wcerr.imbue(std::locale()); std::wcerr << "File name in wide encoding: " << p.wstring() << '\n'; fs::remove(p); }
Possible output:
File contents File name in narrow multibyte encoding: 要らない.txt File name in wide encoding: 要らない.txt
