28 * TIFF Library Macintosh-specific routines.
29 *
30 * These routines use only Toolbox and high-level File Manager traps.
31 * They make no calls to the THINK C "unix" compatibility library. Also,
32 * malloc is not used directly but it is still referenced internally by
33 * the ANSI library in rare cases. Heap fragmentation by the malloc ring
34 * buffer is therefore minimized.
35 *
36 * O_RDONLY and O_RDWR are treated identically here. The tif_mode flag is
37 * checked in TIFFWriteCheck().
38 *
39 * Create below fills in a blank creator signature and sets the file type
40 * to 'TIFF'. It is much better for the application to do this by Create'ing
41 * the file first and TIFFOpen'ing it later.
42 * ---------
43 * This code has been "Carbonized", and may not work with older MacOS versions.
44 * If so, grab the tif_apple.c out of an older libtiff distribution, like
45 * 3.5.5 from www.libtiff.org.
