object by moving all contents from another std::basic_syncbuf
object rhs
, including the temporary storage, the wrapped stream pointer, policy, and all other state (such as the mutex pointer). After move, rhs
is not associated with a stream, and rhs.get_wrapped() == nullptr
. The put area member pointers of the base class std::basic_streambuf
of rhs
are guaranteed to be null. Destroying a moved-from rhs
will not produce any output.obuf | - | pointer to the std::basic_streambuf to wrap |
