ostrstream problems

[wey97]

how do you clear or empty an ostrstream?

#include <windows.h>
#include <strstream>

using namespace std;

void main(){

	ostrstream oss;

	oss << "3.14159265359" << ends;

	MessageBox(0, oss.str(), "", 0);


	// now clear out the stream so a new stream can be written


	oss << "1.41421356237" << ends; 

	MessageBox(0, oss.str(), "", 0);

}
