Module Name:
|
|
|
|
clusinfo.c
|
|
|
|
Abstract:
|
|
|
|
Retrieves cluster information: net name and TCP/IP address.
|
|
|
|
Public functions from this module:
|
|
|
|
bGetClusterNameInfo
|
|
|
|
This code is a total hack. It relies on internal knowledge about
|
|
the registry structure of clustering and NetworkName and TCP/IP adddress:
|
|
|
|
Questionable Assumptions:
|
|
|
|
Directly under the resource GUID there will be a value called
|
|
"Type" that holds the fixed resource name string.
|
|
|
|
The resource type names "Network Name" and "IP Address" will
|
|
never change or be localized. (They shouldn't be localized, since
|
|
they are keys, but I don't see a description value in the registry.)
|
|
|
|
There will be a key called "Parameters" that will never change
|
|
(or get localized).
|
|
|
|
Bad Assumptions:
|
|
|
|
IP Address resource stores a value "Address" that holds
|
|
a REG_SZ string of the tcpip address.
|
|
|
|
Network Name resource stores a value "Name" that holds a REG_SZ
|
|
string of the network name.
|
|
|
|
General strategy:
|
|
|
|
1. Open self resource based on resource string from SplSvcOpen.
|
|
2. Enumerate dependencies looking for net name.
|
|
3. Find net name and save group name.
|
|
4. Enumerate dependencies of net name looking for IP addresses.
|
|
5. Save all found IP addresses.

Routine Description:
|
|
|
|
This routine processes the dependent resources of the main resource.
|

It is called once for each.
|
|
|
|
When we encounter net name, we'll do the same procedure except
|
|
look for tcpip addresses.
|

|
|
Arguments:
|
|
|
|
hResource - This resource is an enumerated dependency.
|
|
|
|
hData - User supplied ata.
|
|
|
|
Return Value:
|
|
|
|
TRUE - Found
|
|
FALSE - Not found.
