DESCRIPTION

28       intmax_t  is a signed integer type capable of representing any value of
29       any basic signed integer type supported by the implementation.   It  is
30       capable of storing values in the range [INTMAX_MIN, INTMAX_MAX].
31
32       uintmax_t is an unsigned integer type capable of representing any value
33       of any basic unsigned integer type supported by the implementation.  It
34       is capable of storing values in the range [0, UINTMAX_MAX].
35
36       The macros [U]INTMAX_WIDTH expand to the width in bits of these types.
37
38       The  macros  [U]INTMAX_MAX expand to the maximum value that these types
39       can hold.
40
41       The macro INTMAX_MIN expands to the minimum  value  that  intmax_t  can
42       hold.
43
44       The  macros  [U]INTMAX_C() expand their argument to an integer constant
45       of type [u]intmax_t.
46
47       The length modifier for [u]intmax_t for the printf(3) and the  scanf(3)
48       families of functions is j; resulting commonly in %jd, %ji, %ju, or %jx
49       for printing [u]intmax_t values.

BUGS
