< cpp‎ | io‎ | basic filebuf
(since C++11)
std::basic_filebuf& operator=( const std::basic_filebuf& rhs ) = delete;

Assigns another basic_filebuf object.

1) First calls close() to close the associated file, then moves the contents of rhs into *this: the put and get buffers, the associated file, the locale, the openmode, the is_open flag, and any other state. After the move, rhs is not associated with a file and rhs.is_open() == false.
2) The copy assignment operator is deleted; basic_filebuf is not CopyAssignable.


[edit] Parameters

rhs - another basic_filebuf that will be moved from

[edit] Return value


[edit] Example

#include <fstream>
#include <string>
#include <iostream>
int main()
    std::ifstream fin(""); // read-only
    std::ofstream fout("test.out"); // write-only
    std::string s;
    getline(fin, s);
    std::cout << s << '\n'; // output
    *fin.rdbuf() = std::move(*fout.rdbuf());
    getline(fin, s);
    std::cout << s << '\n'; // empty line
    std::cout << std::boolalpha << fout.is_open() << '\n'; // prints "false"
