(1) (since C++11)
std::basic_stringbuf& operator=( const std::basic_stringbuf& rhs ) = delete;
(2)
1) Move assignment operator: Moves the contents of rhs into *this. After the move, lhs has the associated string, the open mode, the locale, and all other state formerly held by rhs. The six pointers of std::basic_streambuf in lhs are guaranteed to be different from the corresponding pointers in the moved-from rhs unless null.
2) The copy assignment operator is deleted; basic_stringbuf is not CopyAssignable.

[edit] Parameters

rhs - another basic_stringbuf that will be moved from

[edit] Return value

*this

[edit] Example

#include <sstream>
#include <string>
#include <iostream>
 
int main()
{
 
    std::istringstream one("one");
    std::ostringstream two("two");
 
    std::cout << "Before move, one = \"" << one.str() << '"'
              << " two = \"" << two.str() << "\"\n";
 
    *one.rdbuf() = std::move(*two.rdbuf());
 
    std::cout << "Before move, one = \"" << one.str() << '"'
              << " two = \"" << two.str() << "\"\n";
}

Output:

Before move, one = "one" two = "two"
Before move, one = "two" two = ""
