Arduino inet_aton函数

Question

我正在尝试在Arduino上构建TCP服务器，并且我使用https://github.com/sparkfun/CC3000_WiFi_Breakout库来获取CC3000 WiFi模块（Sparkfun）。

}

utility / socket.h的代码片段

typedef struct _in_addr_t
{
    unsigned long s_addr;                   // load with inet_aton()
} in_addr;

typedef struct _sockaddr_t
{
    unsigned short int    sa_family;
    unsigned char     sa_data[14];
} sockaddr;

typedef struct _sockaddr_in_t
{
    short            sin_family;            // e.g. AF_INET
    unsigned short   sin_port;              // e.g. htons(3490)
    in_addr          sin_addr;              // see struct in_addr, below
    char             sin_zero[8];           // zero this if you want to
} sockaddr_in;

我需要设置sck_addr.sin_addr，但这个库缺少inet_aton函数。

我尝试从Arduino以太网库导入dns库（已定义inet_aton），但inet_aton仍未被识别。
