# CommAddr

#### 功能说明

通信设备地址描述结构体。


#### 定义原型

```
constexpr uint32_t COMM_ADDR_EID_LEN = 16;
typedef struct {
CommAddrType type;         /* 通信地址类别 */
union {
uint8_t raws[36];      /* 通用数据 */
struct in_addr addr;   /* IPv4地址结构 */
struct in6_addr addr6; /* IPv6地址结构 */
uint32_t id;           /* 标识 */
uint8_t eid[COMM_ADDR_EID_LEN];  /* EID地址类型 */
};
} CommAddr;
```
