D.7.4.1 strstream constructors [depr.strstream.cons]

strstream();
Effects: Constructs an object of class strstream, initializing the base class with iostream(&sb).
strstream(char* s, int n, ios_base::openmode mode = ios_base::in|ios_base::out);
Effects: Constructs an object of class strstream, initializing the base class with iostream(&sb) and initializing sb with one of the two constructors:
  • If (mode & app) == 0, then s shall designate the first element of an array of n elements.
    The constructor is strstreambuf(s,n,s).
  • If (mode & app) != 0, then s shall designate the first element of an array of n elements that contains an ntbs whose first element is designated by s.
    The constructor is strstreambuf(s,n,s + std​::​strlen(s)).
