第二种：
struct platform_device_id idt[] = {
{.name = "platform_demo0"},
{.name = "platform_demo1"},
};第三种：
struct sockaddr_in serveraddr ={
.sin_family = AF_INET,
.sin_addr.s_addr = inet_addr("192.168.1.100"),
.sin_port = htons(8888),
};第四种：
struct sockaddr_in serveraddr;
bzero(&serveraddr,sizeof(serveraddr));
serveraddr.sin_family = AF_INET;
serveraddr.sin_addr.s_addr = inet_addr("192.168.1.100");
serveraddr.sin_port = htons(8888);原文：http://blog.51cto.com/5468775/2093271
