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 <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!
