std::basic_osyncstream<CharT,Traits,Allocator>::get_wrapped: std::basic_osyncstream<CharT,Traits,Allocator>::get_wrapped

NAME

std::basic_osyncstream<CharT,Traits,Allocator>::get_wrapped - std::basic_osyncstream<CharT,Traits,Allocator>::get_wrapped

Synopsis


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 <syncstream>
  #include <iostream>
  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!
