basic_opstream public construct/copy/destruct

  1. basic_opstream();
    Default constructor.
  2. basic_opstream(const basic_opstream &) = delete;
    Copy constructor.
  3. basic_opstream(basic_opstream && lhs);
    Move constructor.
  4. basic_opstream(pipe_type && p);
    Move construct from a pipe.
  5. basic_opstream(const pipe_type & p);
    Copy construct from a pipe.
  6. basic_opstream & operator=(const basic_opstream &) = delete;
    Copy assignment.
  7. basic_opstream & operator=(basic_opstream && lhs);
    Move assignment.
  8. basic_opstream & operator=(pipe_type && p);
    Move assignment of a pipe.
  9. basic_opstream & operator=(const pipe_type & p);
    Copy assignment of a pipe.

basic_opstream public member functions

  1. basic_pipebuf< CharT, Traits > * rdbuf() const;
    Get access to the underlying stream_buf.
  2. void pipe(pipe_type && p);
    Set the pipe of the streambuf.
  3. void pipe(const pipe_type & p);
    Set the pipe of the streambuf.
  4. pipe_type & pipe();
    Get a reference to the pipe.
  5. const pipe_type & pipe() const;
    Get a const reference to the pipe.
  6. pipe_type && pipe();
    Get a rvalue reference to the pipe. Qualified as rvalue.
  7. void open();
    Open a new pipe.
  8. void open(const std::string & name);
    Open a new named pipe.
  9. void close();
    Flush the buffer & close the pipe.
