Routine Description:

    Startup a particular resource type. This means verifying the version
    requested, and returning the function table for this resource type.

Arguments:

    ResourceType - Supplies the type of resource.

    MinVersionSupported - The minimum version number supported by the cluster
                    service on this system.

    MaxVersionSupported - The maximum version number supported by the cluster
                    service on this system.

    SetResourceStatus - xxx

    LogEvent - xxx

    FunctionTable - Returns the Function Table for this resource type.

Return Value:

    ERROR_SUCCESS if successful.

    A Win32 error code on failure.
