GetEffectivePermission method of the CIM_DataFile class

The GetEffectivePermission method determines whether the caller has the aggregated permissions on the CIM_DataFile object, and the share on which the file or directory resides, as specified by the Permission argument. This method is inherited from CIM_LogicalFile.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.

Syntax


boolean GetEffectivePermission(
  [in]  uint32 Permissions
);
