[in] Pointer to the network address for the host. Host
addresses are stored in network byte order.
len
[in] Length of the address.
type
[in] Type of the address.
buf
[out] Pointer to the data area to receive the hostent data. The data area must be larger than
the size of a hostent structure because the supplied data
area is used by Windows Sockets to contain a hostent
structure and all of the data referenced by members of the
hostent structure. A buffer of MAXGETHOSTSTRUCT bytes is
recommended.
buflen
[in, out] On input, specifies the size of the data area for the
buf parameter. If the buffer is too small, the error code
HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER) is returned and the
buflen parameter receives the size of the required
buffer.
Return Values
S_OK
Success, the buffer was filled with the host information.
HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER)
Insufficient buffer space was provided. That is, the buffer
pointed to by the buf parameter is not large enough to
contain the host information. For more information, see the
description of the buflen parameter.
HRESULT_FROM_WIN32(WSAHOST_NOT_FOUND)
The address specified could not be found in the relevant
database.
HRESULT_FROM_WIN32(WSATRY_AGAIN)
No response was received from an authoritative server.
HRESULT_FROM_WIN32(WSANO_DATA)
The address specified is valid and was found in the database,
but no information of the type requested is associated with
it.
Remarks
Unlike the IFWXSession::GetHostByAddr
method, this method does not check permissions or policy rules,
does not log the name resolution, and cannot use autodial to dial
out for the name resolution.
