basic_osyncstream::rdbuf

basic_osyncstream::get_wrapped

basic_osyncstream::emit

 

basic_osyncstream& operator=( std::basic_osyncstream&& other) noexcept;

Move-assigns a synchronized output stream:

First, calls emit(). If an exception is thrown by the call to emit(), it is caught and ignored.

Then, move-assigns the wrapped std::basic_syncbuf from the corresponding member of other (after this move-assignment, other.get_wrapped() returns a null pointer and destruction of other produces no output) and move-assigns the base std::basic_ostream (this swaps all stream state variables except for rdbuf between *this and other)

Parameters

other

-

another osyncstream to move from

(constructor)	constructs a basic_osyncstream (public member function)
(destructor)	destroys the basic_osyncstream and emits its internal buffer (public member function)
emit	calls emit on the underlying basic_syncbuf to transmit its internal data to the final destination (public member function)
