Synopsis:
    #include <io.h>
    #include <fcntl.h>
    int setmode( int handle, int mode );

Description:
    The setmode function sets, at the operating system level, the
    translation mode to be the value of mode for the file whose file handle
    is given by handle.  The mode, defined in the <fcntl.h> header file, can
    be one of:

    O_TEXT
        On input, a carriage-return character that immediately precedes a
        linefeed character is removed from the data that is read.  On
        output, a carriage-return character is inserted before each linefeed
        character.

    O_BINARY
        Data is read or written unchanged.


Returns:
    If successful, the function returns the previous mode that was set for
    the file; otherwise, -1 is returned.  When an error has occurred,  errno
    contains a value indicating the type of error that has been detected.

          setmode( fileno( fp ), O_BINARY );
          count = 0L;
          while( fgetc( fp ) != EOF ) ++count;
          printf( "File contains %lu characters\n",
                  count );
          fclose( fp );
