Provider::ValidateQueryFlags method (provider.h)

[The Provider class is part of the WMI Provider Framework which is now considered in final state, and no further development, enhancements, or updates will be available for non-security related issues affecting these libraries. The MI APIs should be used for all new development.]

The ValidateQueryFlags method determines whether a set of flags is valid for a query operation.


HRESULT ValidateQueryFlags(
  long lFlags



Bitmask of flags that are validated.

Return value

Returns WBEM_S_NO_ERROR if the flags are valid and WBEM_E_UNSUPPORTED_PARAMETER if one or more flags are not valid.


At present, the Provider class does not support any query flags. Therefore, if lFlags is set to a value other than zero (0), Provider::ValidateQueryFlags automatically returns WBEM_E_UNSUPPORTED_PARAMETER.

Framework providers must override this method to validate flags that are unknown to the base Provider class.
