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. 46 */ 47 48#include "tiffiop.h" 49#include <Errors.h> 50#include <Files.h> 51#include <Memory.h> 52#include <Script.h> 53 54#if defined(__PPCC__) || defined(__SC__) || defined(__MRC__) || defined(applec) 55#define CtoPstr c2pstr 56#endif 57 58static tsize_t 59_tiffReadProc(thandle_t fd, tdata_t buf, tsize_t size) 60{ 61 return (FSRead((short) fd, (long*) &size, (char*) buf) == noErr ?
