/*
* 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.
