This structure is used by functions to store information about a given host, such as host name, IP address, and so forth. An application should never attempt to modify this structure or to free anything inside the structure. Furthermore, only one copy of this structure is allocated per thread, and an application should therefore copy any information that it needs before issuing any other Windows Sockets API calls.
Syntax
struct hostent { char FAR* h_name; char FAR* FAR* h_aliases; short h_addrtype; short h_length; char FAR* FAR* h_addr_list; }; |

Null-terminated array of alternate names.
- h_addrtype
-
Type of address being returned.
- h_length
-
Length of each address, in bytes.
