Question

帮忙编程 IP地址到计算机名的转换 c++ 或 vc++

Answer 1

使用函数 gethostbyaddr()
struct HOSTENT* FAR gethostbyaddr(
const char* addr,
int len,
int type
);
typedef struct hostent {
char FAR* h_name;
char FAR FAR** h_aliases;
short h_addrtype;
short h_length;
char FAR FAR** h_addr_list;
} hostent;
struct hostent myHost;
myHost = gethostbyaddr("192.168.0.1",4, AF_INET);
string myHostName;
myHostName=myHost.h_name;
