strcpy(pszIpAddr, inet_ntoa(*(struct in_addr *)*host->h_addr_list) );求解释,该怎么处

strcpy(pszIpAddr, inet_ntoa(*(struct in_addr *)*host->h_addr_list) );求解释
strcpy(pszIpAddr, inet_ntoa(*(struct in_addr *)*host->h_addr_list) );

具体的，谢谢，主要是参数都是做什么的，看了百度百科有点迷糊了，尤其是这个‘->’的意思，以前没见过啊

[解决办法]

C/C++ code

strcpy(    pszIpAddr,    inet_ntoa(        *            (struct in_addr *)                *                    host->h_addr_list    ));
[解决办法]
host->h_addr_list

*(host->h_addr_list)

(struct in_addr *)*(host->h_addr_list)

*(struct in_addr *)*(host->h_addr_list)


看清楚4个步骤， 然后看看结构体：

C/C++ code
              struct hostent {                      char    *h_name;        /* official name of host */                      char    **h_aliases;    /* alias list */                      int     h_addrtype;     /* host address type */                      int     h_length;       /* length of address */                      char    **h_addr_list;  /* list of addresses */              }              #define h_addr  h_addr_list[0]  /* for backward compatibility */
