How do I flush a strstream buffer so that the next time I call .str() I
get back an empty string?
Thanks

Just put an empty string in it.
#include <cstdlib>
#include <sstream>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
stringstream s;
s << "Blah";
cout << "1: " << s.str() << "." << endl;
s.str("");
cout << "2: " << s.str() << "." << endl;
system("PAUSE");
return EXIT_SUCCESS;
}

Do you really need to use the old char* based streams? In a stringstream,
(std::string-based stream) you simply do
ss.str(""); ss.clear();
and it's fine. The old (strstream) most likely won't work like that.

Yeah I actually meant stringstream. I don't use strstream. Anyway
funny that the solution is so trivial. I looked in MSDN help for ages
(using Visual C++) and it honest to god just doesn't mention that
overload of the str() function. And I type so fast I've just never
noticed the intellisense pop up when i type the ( to see that it has an
overloaded version. I've been wondering about that question for longer
than I care to admit but it never affected me to the point I had to ask
on a forum. Now I feel dumb, hehe.

Really? From the help file with my VC++v6.0:
basic_stringstream
template <class E,
class T = char_traits<E>,
class A = allocator<E> >
class basic_stringstream : public basic_iostream<E, T> {
public:
explicit basic_stringstream(ios_base::openmode mode = ios_base::in |
ios_base::out);
explicit basic_stringstream(const basic_string<E, T, A>& x,
ios_base::openmode mode = ios_base::in | ios_base::out);
basic_stringbuf<E, T, A> *rdbuf() const;
basic_string<E, T, A>& str();
void str(const basic_string<E, T, A>& x);
};
Looks like two overloads to me. :-)

Hey, don't laugh! I must have stared at that code for 2-3 minutes before I
spotted that first overload. Which is why, I think, my boss always formats
his code so that the identifiers (i.e., "str" in this case) line up in a
single column. It's too weird for me, but at least he can find the member
names quickly.

Long, long ago, in a galaxy far far away, I was told that
essential to programming is attention to detail. I've
never forgotten that. :-)

What? No dorm? Must be a really good school if it was worth
the commute :-) This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
