43 * The following typedefs define the intrinsic size of

46 * in tiff.h. Note also that the varargs interface used
47 * to pass tag types and values uses the types defined in
48 * tiff.h directly.
49 *
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
56 * return -1.
57 * NB: toff_t is not off_t for many reasons; TIFFs max out at
80ed523f
VZ		 58 * 32-bit file offsets, and BigTIFF maxes out at 64-bit
59 * offsets being the most important, and to ensure use of
