重复定义问题，
将#include&&windows.h&放在#include&winsock2.h&之后即可。
CopyRight 2014-最近在看网络编程部分内容，刚开始接触结构体struct sockaddr和struct sockaddr_in的时候，极其迷惑，在网上翻了不少帖子，慢慢有那么点清晰了。呵呵，现在结合一篇网友的文章，对这两个结构体进行解读。在linux环境下，结构体struct sockaddr在/usr/include/linux/socket.h中定义，具体如下：typedef unsigned short sa_family_t;struct sockaddr {&&&&&&& sa_family_t&&&& sa_&&& /* address family, AF_xxx&&&&&& */&&&&&&& char&&&&&&&&&&& sa_data[14];&&& /* 14 bytes of protocol address */
}在linux环境下，结构体struct sockaddr_in在/usr/include/netinet/in.h中定义，具体如下：/* Structure describing an Internet socket address. */struct sockaddr_in{&&& __SOCKADDR_COMMON (sin_);&&& in_port_t sin_&&&&&&&&&&&&&&&&&&&& /* Port number. */&&& struct in_addr sin_&&&&&&&&&&& /* Internet address. */&&& /* Pad to size of `struct sockaddr'. */&&& unsigned char sin_zero[sizeof (struct sockaddr) -&&&&&&&&&&&&&&&&&&&&&&&&&& __SOCKADDR_COMMON_SIZE -&&&&&&&&&&&&&&&&&&&&&&&&&& sizeof (in_port_t) -&&&&&&&&&&&&&&&&&&&&&&&&&& sizeof (struct in_addr)];&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& /* 字符数组sin_zero[8]的存在是为了保证结构体struct sockaddr_in的大小和结构体struct sockaddr的大小相等 */};struct sockaddr是通用的套接字地址，而struct sockaddr_in则是internet环境下套接字的地址形式，二者长度一样，都是16个字节。二者是并列结构，指向sockaddr_in结构的指针也可以指向sockaddr。一般情况下，需要把sockaddr_in结构强制转换成sockaddr结构再传入系统调用函数中。下面是struct sockaddr_in中用到两个数据类型，具体定义如下：/* Type to represent a port. */typedef uint16_t in_port_t;&struct in_addr其实就是32位IP地址struct in_addr {&&&&&&& unsigned long s_};BSD网络软件中包含了两个函数，用来在二进制地址格式和点分十进制字符串格式之间相互转换，但是这两个函数仅仅支持IPv4。&&&&&& in_addr_t inet_addr(const char *cp);&&&&&& char *inet_ntoa(struct in_addr in);功能相似的两个函数同时支持IPv4和IPv6&&&&&& const char *inet_ntop(int domain, const void *addr, char *str, socklen_t size);&&& && int inet_pton(int domain, const char *str, void *addr);通常的用法是：struct sockaddr_in my_sockfd = socket(AF_INET, SOCK_STREAM, 0);&my_addr.sin_family = AF_INET; /* 主机字节序 */my_addr.sin_port = htons(MYPORT); /* short, 网络字节序 */my_addr.sin_addr.s_addr = inet_addr("192.168.0.1");bzero(&(my_addr.sin_zero), 8); /* zero the rest of the struct *///memset(&my_addr.sin_zero, 0, 8);bind(sockfd, (struct sockaddr *)&my_addr, sizeof(struct sockaddr));
