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. */ #include "tiffiop.h" #include #include #include #include #if defined(__PPCC__) || defined(__SC__) || defined(__MRC__) || defined(applec) #define CtoPstr c2pstr #endif static tsize_t _tiffReadProc(thandle_t fd, tdata_t buf, tsize_t size) { return (FSRead((short) fd, (long*) &size, (char*) buf) == noErr ? size : (tsize_t) -1); } static tsize_t _tiffWriteProc(thandle_t fd, tdata_t buf, tsize_t size) { return (FSWrite((short) fd, (long*) &size, (char*) buf) == noErr ? size : (tsize_t) -1); } static toff_t _tiffSeekProc(thandle_t fd, toff_t off, int whence) { long fpos, size; if (GetEOF((short) fd, &size) != noErr) return EOF; (void) GetFPos((short) fd, &fpos); switch (whence) { case SEEK_CUR: if (off + fpos > size) SetEOF((short) fd, off + fpos); if (SetFPos((short) fd, fsFromMark, off) != noErr) return EOF; break; case SEEK_END: if (off > 0) SetEOF((short) fd, off + size); if (SetFPos((short) fd, fsFromStart, off + size) != noErr) return EOF; break; case SEEK_SET: if (off > size) SetEOF((short) fd, off); if (SetFPos((short) fd, fsFromStart, off) != noErr) return EOF; break; } return (toff_t)(GetFPos((short) fd, &fpos) == noErr ? fpos : EOF); } static int _tiffMapProc(thandle_t fd, tdata_t* pbase, toff_t* psize) { return (0); } static void _tiffUnmapProc(thandle_t fd, tdata_t base, toff_t size) { } static int _tiffCloseProc(thandle_t fd) { return (FSClose((short) fd)); } static toff_t _tiffSizeProc(thandle_t fd) { long size; if (GetEOF((short) fd, &size) != noErr) { TIFFErrorExt(fd, "_tiffSizeProc", "%s: Cannot get file size"); return (-1L); } return ((toff_t) size); } /* * Open a TIFF file descriptor for read/writing. */ TIFF* TIFFFdOpen(int fd, const char* name, const char* mode) { TIFF* tif; tif = TIFFClientOpen(name, mode, (thandle_t) fd, _tiffReadProc, _tiffWriteProc, _tiffSeekProc, _tiffCloseProc, _tiffSizeProc, _tiffMapProc, _tiffUnmapProc); if (tif) tif->tif_fd = fd; return (tif); } static void ourc2pstr( char* inString ) { int sLen = strlen( inString ); BlockMoveData( inString, &inString[1], sLen ); inString[0] = sLen; } /* * Open a TIFF file for read/writing. */ TIFF* TIFFOpen(const char* name, const char* mode) { static const char module[] = "TIFFOpen"; Str255 pname; FInfo finfo; short fref; OSErr err; FSSpec fSpec; strcpy((char*) pname, name); ourc2pstr((char*) pname); err = FSMakeFSSpec( 0, 0, pname, &fSpec ); switch (_TIFFgetMode(mode, module)) { default: return ((TIFF*) 0); case O_RDWR | O_CREAT | O_TRUNC: if (FSpGetFInfo(&fSpec, &finfo) == noErr) FSpDelete(&fSpec); /* fall through */ case O_RDWR | O_CREAT: if ((err = FSpGetFInfo(&fSpec, &finfo)) == fnfErr) { if (FSpCreate(&fSpec, ' ', 'TIFF', smSystemScript) != noErr) goto badCreate; if (FSpOpenDF(&fSpec, fsRdWrPerm, &fref) != noErr) goto badOpen; } else if (err == noErr) { if (FSpOpenDF(&fSpec, fsRdWrPerm, &fref) != noErr) goto badOpen; } else goto badOpen; break; case O_RDONLY: if (FSpOpenDF(&fSpec, fsRdPerm, &fref) != noErr) goto badOpen; break; case O_RDWR: if (FSpOpenDF(&fSpec, fsRdWrPerm, &fref) != noErr) goto badOpen; break; } return (TIFFFdOpen((int) fref, name, mode)); badCreate: TIFFErrorExt(0, module, "%s: Cannot create", name); return ((TIFF*) 0); badOpen: TIFFErrorExt(0, module, "%s: Cannot open", name); return ((TIFF*) 0); } void _TIFFmemset(tdata_t p, int v, tsize_t c) { memset(p, v, (size_t) c); } void _TIFFmemcpy(tdata_t d, const tdata_t s, tsize_t c) { memcpy(d, s, (size_t) c); } int _TIFFmemcmp(const tdata_t p1, const tdata_t p2, tsize_t c) { return (memcmp(p1, p2, (size_t) c)); } tdata_t _TIFFmalloc(tsize_t s) { return (NewPtr((size_t) s)); } void _TIFFfree(tdata_t p) { DisposePtr(p); } tdata_t _TIFFrealloc(tdata_t p, tsize_t s) { Ptr n = p; SetPtrSize(p, (size_t) s); if (MemError() && (n = NewPtr((size_t) s)) != NULL) { BlockMove(p, n, GetPtrSize(p)); DisposePtr(p); } return ((tdata_t) n); } static void appleWarningHandler(const char* module, const char* fmt, va_list ap) { if (module != NULL) fprintf(stderr, "%s: ", module); fprintf(stderr, "Warning, "); vfprintf(stderr, fmt, ap); fprintf(stderr, ".\n"); } TIFFErrorHandler _TIFFwarningHandler = appleWarningHandler; static void appleErrorHandler(const char* module, const char* fmt, va_list ap) { if (module != NULL) fprintf(stderr, "%s: ", module); vfprintf(stderr, fmt, ap); fprintf(stderr, ".\n"); } TIFFErrorHandler _TIFFerrorHandler = appleErrorHandler; /* * Local Variables: * mode: c * c-basic-offset: 8 * fill-column: 78 * End: */
