Protected, virtual function to insert elements into the output stream.
virtual streamsize xsputn(
const char_type *_Ptr,
streamsize _Count
);
Parameters
_Ptr
Pointer to elements to insert._Count
Number of elements to insert.
Return Value
The number of elements actually inserted into the stream.
Remarks
The protected virtual member function inserts up to _Count elements into the output stream, as if by repeated calls to sputc, from the array beginning at _Ptr. The insertion of characters into the output stream stops once all _Count characters have been written, or if calling sputc(_Count) would return traits::eof(). It returns the number of elements actually inserted.
