Currently named as hypervObjecUnified to keep code compilable/functional until all bits are in place. This struct is a result of unserializing WMI request response. Therefore, it needs to be able to deal with different "versions" of the same WMI class. To accomplish this, the "data" member was turned in to a union which: * has a "common" member that contains only WMI class fields that are safe to access and are present in all "versions". This is ensured by the code generator that takes care of proper struct memory alignment between "common", "v1", "v2" etc members. This memeber is to be used by the driver code wherever the API implementation can be shared for all supported hyper-v versions. * the "v1" and "v2" member can be used by the driver code to handle version specific cases. Example: Msvm_ComputerSystem *vm = NULL; ... hypervGetVirtualMachineList(priv, wqlQuery, *vm); ... /* safe for "v1" and "v2" */ char *vmName = vm->data.common->Name; /* or if one really needs special handling for "v2" */ if (priv->wmiVersion == HYPERV_WMI_VERSION_V2) { char *foo = vm->data.v2->SomeV2OnlyField; } In other words, driver should not concern itself with existence of "v1" or "v2" of WMI class unless absolutely necessary. --- src/hyperv/hyperv_wmi.h | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/src/hyperv/hyperv_wmi.h b/src/hyperv/hyperv_wmi.h index ce1fe05..5fc36e8 100644 --- a/src/hyperv/hyperv_wmi.h +++ b/src/hyperv/hyperv_wmi.h @@ -41,6 +41,25 @@ int hypervVerifyResponse(WsManClient *client, WsXmlDocH response, /* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Object */ +typedef struct _hypervObjectUnified hypervObjectUnified; +struct _hypervObjectUnified { + /* Unserialized data from wsman response.
