std::filesystem::path::operator= (3) - Linux Man Pages

std::filesystem::path::operator=: std::filesystem::path::operator=

NAME

std::filesystem::path::operator= - std::filesystem::path::operator=

Synopsis


path& operator=( const path& p ); (1) (since C++17)
path& operator=( path&& p ) noexcept; (2) (since C++17)
path& operator=( string_type&& source ); (3) (since C++17)
template< class Source > (4) (since C++17)
path& operator=( const Source& source );


1) Replaces the contents of *this with a pathname whose both native and generic format representations equal those of p.
2) Replaces the contents of *this with a pathname whose both native and generic format representations equal those of p, possibly using move semantics: p is left in a valid, but unspecified state.
3) Replaces the contents of *this with a new path value constructed from detected-format source, which is left in valid, but unspecified state. Equivalent to assign(std::move(source)).
4) Replaces the contents of *this with a new path value constructed from detected-format source as if by overload (4) of the path_constructor. Equivalent to assign(source).

Parameters


p - a path to assign
         a std::basic_string, std::basic_string_view, pointer to a null-terminated character/wide character string, or an input iterator that points to a null-terminated character/wide character sequence. The character type must be one of char,
source - char8_t,
         (since C++20)char16_t, char32_t, wchar_t

Return value


*this

Example


// Run this code


  #include <filesystem>
  namespace fs = std::filesystem;
  int main()
  {
      fs::path p = "C:/users/abcdef/AppData/Local";
      p = p / "Temp"; // move assignment
      const wchar_t* wstr = L"D:/猫.txt";
      p = wstr; // assignment from a source
  }
