42 * The following typedefs define the intrinsic size of
43 * data types used in the *exported* interfaces. These
44 * definitions depend on the proper definition of types
45 * in tiff.h. Note also that the varargs interface used
46 * to pass tag types and values uses the types defined in
47 * tiff.h directly.
48 *
49 * NB: ttag_t is unsigned int and not unsigned short because
50 * ANSI C requires that the type before the ellipsis be a
51 * promoted type (i.e. one of int, unsigned int, pointer,
52 * or double) and because we defined pseudo-tags that are
53 * outside the range of legal Aldus-assigned tags.
54 * NB: tsize_t is int32 and not uint32 because some functions
55 * return -1.
56 * NB: toff_t is not off_t for many reasons; TIFFs max out at
80ed523f
VZ		 57 * 32-bit file offsets, and BigTIFF maxes out at 64-bit
58 * offsets being the most important, and to ensure use of
59 * a consistently unsigned type across architectures.
