Use the System.Security.AccessControl.EventWaitHandleRights enumeration to specify access control rights when you create System.Security.AccessControl.EventWaitHandleAccessRule objects. To apply access rights to a named system event, first add System.Security.AccessControl.EventWaitHandleAccessRule objects to an System.Security.AccessControl.EventWaitHandleSecurity object, then attach the System.Security.AccessControl.EventWaitHandleSecurity object to the named system event using the System.Threading.EventWaitHandle.#ctor(bool, System.Threading.EventResetMode, string, Boolean@, EventWaitHandleSecurity) constructor or the System.Threading.EventWaitHandle.SetAccessControl(EventWaitHandleSecurity) method.
Security on synchronization objects is not supported for Windows 98 or Windows Millennium Edition.
