27 Input/output library [input.output]

27.6 Stream buffers [stream.buffers]

27.6.3 Class template basic_­streambuf [streambuf]

27.6.3.3 Protected member functions [streambuf.protected]

27.6.3.3.1 Assignment [streambuf.assign]

basic_streambuf& operator=(const basic_streambuf& rhs);
Effects: Assigns the data members of rhs to *this.
Ensures:
  • eback() == rhs.eback()
  • gptr() == rhs.gptr()
  • egptr() == rhs.egptr()
  • pbase() == rhs.pbase()
  • pptr() == rhs.pptr()
  • epptr() == rhs.epptr()
  • getloc() == rhs.getloc()
Returns: *this.
void swap(basic_streambuf& rhs);
Effects: Swaps the data members of rhs and *this.

27.6.3.3.2 Get area access [streambuf.get.area]

char_type* eback() const;
Returns: The beginning pointer for the input sequence.
char_type* gptr() const;
Returns: The next pointer for the input sequence.
char_type* egptr() const;
Returns: The end pointer for the input sequence.
void gbump(int n);
Effects: Adds n to the next pointer for the input sequence.
void setg(char_type* gbeg, char_type* gnext, char_type* gend);
Ensures: gbeg == eback(), gnext == gptr(), and gend == egptr().

27.6.3.3.3 Put area access [streambuf.put.area]

char_type* pbase() const;
Returns: The beginning pointer for the output sequence.
char_type* pptr() const;
Returns: The next pointer for the output sequence.
char_type* epptr() const;
Returns: The end pointer for the output sequence.
void pbump(int n);
Effects: Adds n to the next pointer for the output sequence.
void setp(char_type* pbeg, char_type* pend);
Ensures: pbeg == pbase(), pbeg == pptr(), and pend == epptr().
