/*---------------------------------------------------+
|  Redefine the printf style output functions.       |
|  Include stdio.h here so it won't interfere later. |
|  The reason we do this is to cause printf's and    |
|  fprintfs and fwrites to stdout and stderr to be   |
|  redirected to MicroStation's console window so    |
|  they will be visible for debugging purposes. If   |
|  you don't want that behavior, #define NO_IODEFS   |
|  before including basedefs.h. In that case, your   |
|  output to stdout and stderr is not displayed.     |
