- * jmemmac.c

- *

- * Copyright (C) 1992-1997, Thomas G. Lane.

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

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

- *

- * jmemmac.c provides an Apple Macintosh implementation of the system-

- * dependent portion of the JPEG memory manager.

- *

- * If you use jmemmac.c, then you must define USE_MAC_MEMMGR in the

- * JPEG_INTERNALS part of jconfig.h.

- *

- * jmemmac.c uses the Macintosh toolbox routines NewPtr and DisposePtr

- * instead of malloc and free.  It accurately determines the amount of

- * memory available by using CompactMem.  Notice that if left to its

- * own devices, this code can chew up all available space in the

- * application's zone, with the exception of the rather small "slop"

- * factor computed in jpeg_mem_available().  The application can ensure

- * that more space is left over by reducing max_memory_to_use.

- *

- * Large images are swapped to disk using temporary files and System 7.0+'s

- * temporary folder functionality.

- *

- * Note that jmemmac.c depends on two features of MacOS that were first

- * introduced in System 7: FindFolder and the FSSpec-based calls.

- * If your application uses jmemmac.c and is run under System 6 or earlier,

- * and the jpeg library decides it needs a temporary file, it will abort,

- * printing error messages about requiring System 7.  (If no temporary files

- * are created, it will run fine.)

- *

- * If you want to use jmemmac.c in an application that might be used with

- * System 6 or earlier, then you should remove dependencies on FindFolder

- * and the FSSpec calls.  You will need to replace FindFolder with some

- * other mechanism for finding a place to put temporary files, and you

- * should replace the FSSpec calls with their HFS equivalents:

- *

- *     FSpDelete     ->  HDelete

- *     FSpGetFInfo   ->  HGetFInfo

- *     FSpCreate     ->  HCreate

- *     FSpOpenDF     ->  HOpen      *** Note: not HOpenDF ***

- *     FSMakeFSSpec  ->  (fill in spec by hand.)

- *

- * (Use HOpen instead of HOpenDF.  HOpen is just a glue-interface to PBHOpen,

- * which is on all HFS macs.  HOpenDF is a System 7 addition which avoids the

- * ages-old problem of names starting with a period.)

- *

- * Contributed by Sam Bushell (jsam@iagu.on.net) and

- * Dan Gildor (gyld@in-touch.com).
