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 Reading and Writing Preferences Finding an Active EntityListing 2-7 Reading a ﬁxed-size preference Reading Fixed-size PreferencesUsing Network Setup 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 Reading Variable-size Preferences assertdbRef != nil assertentity != nil assertname != nilUsing Network Setup 38 Reading and Writing PreferencesWriting Preferences Iterating the Preferences in an Entity Using Network Setup Reading and Writing PreferencesWorking 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 Protocol-speciﬁc Topics TCP/IP Notesaccess 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 Modem Notes OTCfgRemoteClientLocks pageNotes 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 OTCfgOpenDatabase OTCfgCloseDatabaseManaging Areas OTCfgGetCurrentArea OTCfgSetCurrentArea OTCfgOpenAreaOTCfgCloseArea OTCfgBeginAreaModiﬁcations function resultOTCfgCommitAreaModiﬁcations function resultfunction result OTCfgAbortAreaModiﬁcationsOTCfgIsSameAreaID OTCfgAbortAreaModifications returns kCfgErrAreaNotFoundOTCfgGetAreaName function resultOTCfgSetAreaName function resultOTCfgGetAreasList OTCfgGetAreasCountfunction result that are available.
