C++ implementations should define these macros only when __STDC_LIMIT_MACROS is defined before <stdint.h> is included | |
#define | INT8_MAX 0x7f |
#define | INT8_MIN (-INT8_MAX - 1) |
#define | UINT8_MAX (INT8_MAX * 2 + 1) |
#define | INT16_MAX 0x7fff |
#define | INT16_MIN (-INT16_MAX - 1) |
#define | UINT16_MAX (__CONCAT(INT16_MAX, U) * 2U + 1U) |
#define | INT32_MAX 0x7fffffffL |
#define | INT32_MIN (-INT32_MAX - 1L) |
#define | UINT32_MAX (__CONCAT(INT32_MAX, U) * 2UL + 1UL) |
#define | INT64_MAX 0x7fffffffffffffffLL |
#define | INT64_MIN (-INT64_MAX - 1LL) |

#define | UINT32_C(value) __CONCAT(value, UL) |
#define | INT64_C(value) __CONCAT(value, LL) |
#define | UINT64_C(value) __CONCAT(value, ULL) |
#define | INTMAX_C(value) __CONCAT(value, LL) |
