This routine calls a routine, MyGetEntityUserVisibleName, which hasn’t been documented yet. It is shown in Listing 2-9 in the section “Reading and Writing Preferences” page Finding an Active Entity Reading and Writing PreferencesUsing Network Setup Reading Fixed-size PreferencesListing 2-7 Reading a ﬁxed-size preference Reading and Writing PreferencesThe sample shown in Listing 2-7, which opens and closes the entity before reading each preference, is implemented in an inefﬁcient manner for the sake of clarity. If you are reading multiple preferences, it is more efﬁcient to open the entity once. Then read the preferences by calling OTCfgGetPrefs or OTCfgSetPrefs multiple times and close the entity when you’re done assertdbRef != nil assertentity != nil assertname != nil Reading Variable-size Preferences38 Reading and Writing Preferences Using Network SetupWriting Preferences Iterating the Preferences in an Entity Reading and Writing Preferences Using Network SetupWorking with Sets Finding the Active Set Entity The MyFindActiveSet routine in Listing 2-13 implements the ﬁrst two steps. It starts by getting a list of all of the set entities by calling the MyGetEntitiesList routine Listing 2-5. Then MyFindActiveSet iterates through all of the set entities, reading the kOTCfgSetsStructPref preference of each set entity. That preference maps to the CfgSetsStruct structure, which contains an fFlags member. One bit of the fFlags member, kOTCfgSetsFlagActiveMask, indicates whether this set entity is the active set entity. If it is, the routine breaks out of the loop and returns the set’s entity reference to the caller breaks out of the loop and returns the found entity Listing 2-14 Finding the active entity of a given class and type Using Network Setup46 Working with Sets Listing 2-15 Finding the active TCP/IP entity Using Network SetupWorking with Sets Areas and Sets TCP/IP Notes Protocol-speciﬁc Topicsaccess the preference in its packed format Protocol-speciﬁc Topics Using Network Setupcursor = UInt8 * packedPref 52 Protocol-speciﬁc Topics Using Network SetupUInt8 *cursor Remote Access Notes OTCfgRemoteClientLocks page Modem NotesNotes for Third Parties Network Setup and Third-party Protocol StacksStoring Third-party Preferences in Apple Entities 56 Notes for Third Parties Using Network SetupC H A P T E R Network Setup Functions Network Setup ReferenceOpening and Closing the Network Setup Database OTCfgCloseDatabase OTCfgOpenDatabaseManaging Areas OTCfgGetCurrentArea OTCfgOpenArea OTCfgSetCurrentAreaOTCfgCloseArea function result OTCfgBeginAreaModiﬁcationsfunction result OTCfgCommitAreaModiﬁcationsOTCfgIsSameAreaID OTCfgAbortAreaModiﬁcationsfunction result OTCfgAbortAreaModifications returns kCfgErrAreaNotFoundfunction result OTCfgGetAreaNamefunction result OTCfgSetAreaNameOTCfgGetAreasList OTCfgGetAreasCountfunction result function result that are available.
