/*
 * 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.
