I run into the following problem:

using DJGPP 2.02-2.03 and GCC/GPP 2.81 or 2.95.1
on a plain i386/DOS 6.22 machine
I can not open fstream in BINARY mode,
e.g. I got zero size file from the sample program below.

If this is G++ problem could you forward this message to
GCC/G++ mailing list, please.

It is OK when I use  FILE *fp; fp = open(somename, "wb");
though.

Leonid.



#include <iostream>
#include <fstream>

int main (int argc, char *argv[])
{
        ofstream fpw (argv[1], ios::binary);

        for (int i=0; i<256; i++) {
                fpw.put( ((char)i) );
        }
}
