The WdfWmiProviderIsEnabled method determines if either data collection or event notification is enabled for a specified WMI data provider.
WmiProvider [in]A handle to a WMI provider object that the driver obtained by calling WdfWmiProviderCreate or WdfWmiInstanceGetProvider.
ProviderControl [in]A WDF_WMI_PROVIDER_CONTROL-typed value that specifies one of the types of control functions (data collection or event notification) that a WMI data provider can support.
WdfWmiProviderIsEnabled returns TRUE if the capability that the ProviderControl parameter specifies is enabled and FALSE otherwise.
A bug check occurs if the driver supplies an invalid object handle.
A driver that does not provide an EvtWmiProviderFunctionControl callback function can call WdfWmiProviderIsEnabled to determine if data collection or event notification is enabled.
The following code example determines if event notification is enabled for a specified WMI data provider.
BOOLEAN eventNotifEnabled;
eventNotifEnabled = WdfWmiProviderIsEnabled(
wmiProvider,
WdfWmiEventControl
);
