// If we have access to a file via file name, we can open the file with an
// additional "b" or a O_BINARY within the (f)open function to get a
// transparent untranslated data stream which is necessary for audio bitstream
// data and also for PCM data. If we are working with
// stdin/stdout/FILENO_STDIN/FILENO_STDOUT we can't open the file with this
// attributes, because the files are already open. So we need a non
// standardized sequence to switch to this mode (not necessary for Unix).
// Mostly the sequency is the same for incoming and outgoing streams, but only
// mostly so we need one for IN and one for OUT.
// Macros are called with the file pointer and you get back the untransalted file
// pointer which can be equal or different from the original.
