[Dev-C++] Problem with binary write to a file

[<SAL...@me...>]

Hello,

I've found a very strange behaviour of the fwrite and fputc function.
When I write the "0x0A" character, the function add a "0x0D" character
also.
This is very obvious when you want to write binary values !!!

Can someone help me ?

Here is a very small fonction that show the pb :

Thanks,

#include <stdio.h>
#include <string.h>


void show_pb_write()
{
  FILE *file;
  char buf[10];
  int i;

  buf[0]=3D0x01;
  buf[1]=3D0x02;
  buf[2]=3D0x0A;
  buf[3]=3D0x0A;

  file=3Dfopen("PB.DAT", "w");
  for (i=3D0;i<4;i++)
    {
    fputc(buf[i],file);
    }

  fwrite(buf,1,4,file);
  fclose(file);

}

Instead of writing 8 characters, the file created has 12 characters.
