定义跨平台的数据类型

我们可以这样定义，用int8_t来代替char类型

#if !(__linux__)
typedef signed char               int8_t;
typedef short                     int16_t;
typedef int                       int32_t;
typedef long long                 int64_t;
#endif
typedef unsigned char             uint8_t;
typedef unsigned short            uint16_t;
typedef unsigned int              uint32_t;

typedef unsigned long long        uint64_t;

也可以参照HM12.0中的TypeDef.h

typedef       unsigned __int64    UInt64;
#endif

typedef       long long           Int64;
typedef       unsigned long long  UInt64;
