boolean DOFSystem_IsInterestRequested ( const DOFSystem  self, const DOFObjectID  objectID, const DOFInterfaceID  interfaceID, DOFInterestLevel  level  ) Determine if there is interest currently expressed for a given Object and Interface. If interfaceID is the Wildcard IID, then check for all interfaces on the given Object. If interfaceID is NULL, then check for any interfaces on the given Object. Parameters self The System. This must not be NULL. objectID The Object ID. This should not be NULL. The Broadcast ID only matches interest where the Broadcast ID was used. interfaceID The Interface ID. This may be NULL to indicate any interface ID. The Wildcard ID only matches interest where the Wildcard ID was used. level The level of interest for which to check. Current interest at or above the specified level will return an affirmative result. Returns FALSE if the specified level of interest is not present for the given Object and Interface. TRUE if the specified level of interest is present for the given Object and Interface.
