This structure is allocated by Windows Sockets. An application should never attempt to modify this structure or to free any of its components. Furthermore, only one copy of this structure is allocated per thread, and so the application should copy any information that it needs before issuing any other Windows Sockets API calls.

char FAR * h_name;

char FAR * FAR * h_aliases;

short h_addrtype;

short h_length;

char FAR * FAR * h_addr_list;
