std::filesystem::path::operator=

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 >
path& operator=( const Source& source );
 (4) (since C++17)
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
source - 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, char16_t, char32_t, wchar_t

Return value

*this.

Example

#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
}
