std::basic_...asic_syncbuf(3)  C++ Standard Libary std::basic_...asic_syncbuf(3)

NAME
     std::basic_syncbuf::basic_syncbuf - std::basic_syncbuf::basic_syncbuf

Synopsis
	basic_syncbuf() 					   (1)
	    : basic_syncbuf( nullptr )
	explicit basic_syncbuf( streambuf_type* obuf )		   (2)
	    : basic_syncbuf( obuf, Allocator() ) {}
	basic_syncbuf( streambuf_type* obuf, const Allocator& a ); (3)
	basic_syncbuf( basic_syncbuf&& rhs );			   (4)

	1)  Default  constructor: creates an instance of std::basic_syncbuf with
     emit-on-sync
	policy set to false, wrapped streambuffer set to nullptr, and using
	default-constructed Allocator as the allocator for temporary storage.
	2,3) Creates an instance of std::basic_syncbuf with emit-on-sync  policy
     set to
	false,	wrapped  streambuffer  set to obuf, and using a as the allocator
     for temporary
	storage.
	4) Move constructor: move-constructs a std::basic_syncbuf object by mov-
     ing all
	contents from another std::basic_syncbuf object rhs, including the  tem-
     porary
	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::ba-
     sic_streambuf of rhs
	are guaranteed to be null. Destroying a moved-from rhs will not  produce
     any output.

Parameters
	obuf - pointer to the std::basic_streambuf to wrap
	a    - the allocator to use for temporary storage
	rhs  - another std::basic_syncbuf to move from

Exceptions
	2,3)  May throw std::bad_alloc from the constructor of the internal tem-
     porary storage
	or std::system_error from the mutex construction.

Notes
	Typically called by the appropriate  constructors  of  std::basic_osync-
     stream.

	sync	   synchronizes  the  buffers  with the associated character se-
     quence
	[virtual]  (virtual  protected	member	function  of  std::basic_stream-
     buf<CharT,Traits>)

	emit	  atomically transmits the entire internal buffer to the wrapped
     streambuf
		  (public member function)
