返回一个指向struct HOSTENT的指针。
struct hostent {
char FAR * h_name;
char FAR * FAR * h_aliases;
short h_addrtype;
short h_length;
char FAR * FAR * h_addr_list;
};
h_name
Official name of the host (PC). If using the DNS or similar resolution system, it is the Fully Qualified Domain Name (FQDN) that caused the server to return a reply. If using a local hosts file, it is the first entry after the IP address.
h_aliases
Null-terminated array of alternate names.
h_addrtype
Type of address being returned.
h_length
Length of each address, in bytes.
h_addr_list
Null-terminated list of addresses for the host. Addresses are returned in network byte order. The macro h_addr is defined to be h_addr_list[0] for compatibility with older software.
