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, 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 }
