- * This file contains compression data destination routines for the case of |
- * emitting JPEG data 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. |
