streambuf_type* get_wrapped() const noexcept;

Returns a pointer to the wrapped std::basic_streambuf, obtained by calling get_wrapped() on the underlying std::basic_syncbuf.

Parameters

(none)

Example

Wrapped buffer can be safely wrapped again in a different synchronized output stream.

Run this code
#include <iostream>
#include <syncstream>
 
int main()
{
    std::osyncstream bout1(std::cout);
    bout1 << "Hello, ";
    {
        std::osyncstream(bout1.get_wrapped()) << "Goodbye, " << "Planet!" << '\n';
    } // emits the contents of the temporary buffer
    bout1 << "World!" << '\n';
} // emits the contents of bout1

Output: 

Goodbye, Planet!
Hello, World!
