38 * library's internal data structures from clients.
40 typedef struct tiff TIFF;
43 * The following typedefs define the intrinsic size of
44 * data types used in the *exported* interfaces. These
45 * definitions depend on the proper definition of types
46 * in tiff.h. Note also that the varargs interface used
47 * to pass tag types and values uses the types defined in
50 * NB: ttag_t is unsigned int and not unsigned short because
51 * ANSI C requires that the type before the ellipsis be a
52 * promoted type (i.e. one of int, unsigned int, pointer,
53 * or double) and because we defined pseudo-tags that are
54 * outside the range of legal Aldus-assigned tags.
55 * NB: tsize_t is int32 and not uint32 because some functions
57 * NB: toff_t is not off_t for many reasons; TIFFs max out at
58 * 32-bit file offsets being the most important, and to ensure
59 * that it is unsigned, rather than signed.
