basic_stringbuf basic_stringbuf<Char,Traits,Allocator>(mode).:
Constructs new underlying string device. The underlying
basic_stringbuf object is constructed as basic_stringbuf<Char,Traits,Allocator>(mode).2)
str . basic_stringbuf basic_stringbuf<Char,Traits,Allocator>(str, mode).:
Uses a copy of
str as initial contents of the underlying string device. The underlying basic_stringbuf object is constructed as basic_stringbuf<Char,Traits,Allocator>(str, mode).3)

Move constructor. Constructs the file stream with the state of
other using move semantics. | str | ,
