+ * Copyright (C) 1994-1996, Thomas G. Lane.

+ * Modified 2009 by Guido Vollbeding.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file contains compression data destination routines for the case of

+ * emitting JPEG data to memory or to a file (or any stdio stream).

+ * While these routines are sufficient for most applications,

+ * some will want to use a different destination manager.

+ * IMPORTANT: we assume that fwrite() will correctly transcribe an array of

+ * JOCTETs into 8-bit-wide elements on external storage.  If char is wider

+ * than 8 bits on your machine, you may need to do some tweaking.
