ostrstream();
ostrstream(char *s, streamsize n,
ios_base::openmode mode = ios_base::out);
Both constructors initialize the base class by calling ostream
(sb)
, where sb
is the stored object of class
strstreambuf
. The first constructor also initializes sb
by calling strstreambuf
()
. The second constructor initializes
the base class one of two ways:
mode & ios_base::
app
== 0
, then s
must designate the first element of an array of n
elements, and the
constructor calls strstreambuf(s, n, s)
.s
must designate the first element of an array of n
elements that contains a C string whose first
element is designated by s
, and the constructor calls strstreambuf(s, n, s +
strlen
(s)
.
