* FUNCTION : CPCH_NetworkProtocol::EnumerateInstances
|
|
*
|
|
* DESCRIPTION : Returns all the instances of this class.
|
|
*
|
|
* INPUTS : A pointer to the MethodContext for communication with WinMgmt.
|
|
* A long that contains the flags described in
|
|
* IWbemServices::CreateInstanceEnumAsync. Note that the following
|
|
* flags are handled by (and filtered out by) WinMgmt:
|
|
* WBEM_FLAG_DEEP
|
|
* WBEM_FLAG_SHALLOW
|
|
* WBEM_FLAG_RETURN_IMMEDIATELY
|
|
* WBEM_FLAG_FORWARD_ONLY
|
|
* WBEM_FLAG_BIDIRECTIONAL
|
|
*
|
|
* RETURNS : WBEM_S_NO_ERROR if successful
|
|
*
|
|
* COMMENTS : TO DO: All instances on the machine should be returned here.
|
|
* If there are no instances, return WBEM_S_NO_ERROR.
|
|
* It is not an error to have no instances.
