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