NAME¶

std::basic_osyncstream::get_wrapped - std::basic_osyncstream::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 <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!
