C 库函数 - memcpy()
https://www.runoob.com/cprogramming/c-function-memcpy.html
自己实现：
#include<stdio.h>
#include<arpa/inet.h>

void typeorder()
{
union
{
short value;
char array[sizeof(short)];
}test;
test.value=0x0102;
if(test.array[0]==1)
printf(“host is 大端\n”);
else
printf(“host is little duan\n”);

}

int main()
{
typeorder();
//char * value1 = inet_aton(“192.168.0.102”,);
struct in_addr addr1,addr2;
unsigned int l1,l2;
l1=inet_addr(“192.168.0.74”);
l2=inet_addr(“211.56.65.32”);

    printf("l1=%d\n",l1);
    memcpy(&addr1,&l1,4);
    memcpy(&addr2,&l2,4);
    char * value1 = inet_ntoa(addr1);
    char * value2 = inet_ntoa(addr2);

    printf("1:%s\n",value1);
    printf("2:%s\n",value2);
    return 0;

}
实现结果
