RE: Problem with fstream.

["Thumas, Herve" <Herve dot Thumas at lms dot be>]

Hi,

Following your different answers, I think that I've found a solution.

I've tried with the both notations and the problem is the same.

No, this file doesn't exist. But with previous versions of g++, if the file
didn't exist, it was created by the 'new fstream'.

So I've adapted my code. I first check if my file exists and if not I create
it with a "f.open(filename, ios::out)" (See code below).

-------------------------------------------------

#include <stdio.h>
#include <iostream.h>
#include <fstream.h>

int main(void)
{
   fstream *f;
   fstream ftst;
   char filename[256];

   sprintf(filename,"//D/tst.log");
   ftst.open(filename,ios::in);
   if(!ftst.good())
   {
      ftst.close();
      ftst.open(filename,ios::out);
   }
   ftst.close();
   
   f = new fstream(filename, ios::in | ios::out );

   if(f->good())
      printf("f ok\n");
   else
      printf("f nok\n");

   return 0;
}

-------------------------------------------------

Thank you for your help,
Hervé.
