uintmax_t and intmax_t
are the largest integer
types of at least 64 bits.
uintmax_t is unsigned, and has the range zero
to UINTMAX_,
which is at least [0, +18446744073709551615]. intmax_t
is signed, and has the range INTMAX_
to INTMAX_,
which is at least [−9223372036854775807,
+9223372036854775807].
The following macros can be used in the fmt argument of printf to print arguments of types
uintmax_t and intmax_t:
PRIuMAXPRIoMAXPRIxMAXPRIXMAXPRIdMAXPRIiMAX
The following macros can be used in the fmt argument of scanf to scan arguments of types
uintmax_t * and intmax_t
*:

atomic_
is an alias for _Atomic
uintmax_t. atomic_
is an alias for _Atomic intmax_t.
