结构体变量初始化

第一种：
struct resource res[] = {
[0]={
.start = 0x10001000,
.end   = 0x10001004,
.flags = IORESOURCE_MEM,
},

[1] = {
.start = 0x20001000,
.end   = 0x20001004,
.flags = IORESOURCE_MEM,
},
};

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);
