Re: ios::ate in gcc3.4.2

Hi Li Qihong,

Do this...
------------------------------
#include <iostream>
#include <fstream>

using std::fstream;
using std::ios_base;

int main()
{
    fstream f;
    f.open("1", ios_base::in | ios_base::out | ios_base::ate);
//  f.seekp(0, ios_base::end); -- unnecessary w/ios_base::ate
    f << "Haha";
    f.close();
}
---------------------------------

You didn't specify the ios_base::in, which will prevent the ios_base::out 
from performing an ios_base::trunc for you.

Alternatively, you could do...

    f.open("1", ios_base::out | ios_base::app);

...the ios_base::ate is redundant.

Please see p639 of Stroustrup's C++ Programming Language (special edition).

HTH,
