基础数据类型
宏定义
#define OS_UINT8_MAX 0xff
#define OS_UINT16_MAX 0xffff
#define OS_UINT32_MAX 0xffffffff
#define OS_UINT64_MAX 0xffffffffffffffffULL
#define OS_TICK_MAX OS_UINT32_MAX
数据类型重定义
内核使用自己重定义的基本数据类型，具体如下：
typedef signed char os_int8_t;
typedef signed short os_int16_t;
typedef signed int os_int32_t;
typedef signed long long os_int64_t;
typedef unsigned char os_uint8_t;
typedef unsigned short os_uint16_t;
typedef unsigned int os_uint32_t;
typedef unsigned long long os_uint64_t;
typedef signed int os_bool_t;
typedef signed long os_base_t;
typedef unsigned long os_ubase_t;
typedef os_int32_t os_err_t;
typedef os_uint32_t os_tick_t;
typedef os_ubase_t os_size_t;
typedef os_base_t os_off_t;
某些数据类型补充说明如下：
| 类型 | 说明 |
|---|---|
| os_base_t | CPU位数相关长整型数据类型 |
| os_ubase_t | CPU位数相关无符号长整型数据类型 |
| os_err_t | 错误码数据类型 |
| os_tick_t | 系统时钟节拍数据类型 |
| os_size_t | 字节大小数据类型 |
| os_off_t | 偏移数据类型 |
