Network Setup Protocol Structures and Data Types

OTCfgIRGeneral

The OTCfgIRGeneral structure stores per-connection infrared settings.

struct OTCfgIRGeneral

{

UInt32 fVersion;

OTPortRef fPortRef;

OTCfgIRPortSettingfPortSetting;

Boolean fNotifyOnDisconnect;

Boolean fDisplayIRControlStrip;

};
Field descriptions
fVersion	Must be zero.
fPortRef	Reference to the infrared port.

OTCfgIRPortSetting A value that speciﬁes the infrared protocol. For possible values, see the OTCfgIRPortSetting (page 174) enumeration.

fNotifyOnDisconnect

TRUE if the user is to be notiﬁed when the IrDA protocol disconnects; otherwise, FALSE.

fDisplayIRControlStrip

TRUE if the Infrared control strip is to be displayed; otherwise, FALSE.

The preference type for the OTCfgIRGeneral structure is kOTCfgIRGeneralPref, which is deﬁned as 'atpf'.

Protocol Constants and Other Data Types

The following sections describe constants and other data types that are deﬁned for the protocols that use Network Setup:

■“TCP/IP Constants and Other Data Types” (page 160)

■“Apple Remote Access Constants and Other Data Types” (page 163)

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 PreferencesReading and Writing Preferences Reading Fixed-size PreferencesUsing Network Setup Listing 2-7 Reading a ﬁxed-size preferenceThe 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 Using Network Setup Listing 2-14 Finding the active entity of a given class and type46 Working with Sets Using Network Setup Listing 2-15 Finding the active TCP/IP entityWorking with Sets Areas and Sets TCP/IP Notes Protocol-speciﬁc Topicsaccess the preference in its packed format Using Network Setup Protocol-speciﬁc Topicscursor = UInt8 * packedPref Using Network Setup 52 Protocol-speciﬁc TopicsUInt8 *cursor Remote Access Notes OTCfgRemoteClientLocks page Modem NotesNetwork Setup and Third-party Protocol Stacks Notes for Third PartiesStoring Third-party Preferences in Apple Entities Using Network Setup 56 Notes for Third PartiesC H A P T E R Network Setup Reference Network Setup FunctionsOpening and Closing the Network Setup Database OTCfgCloseDatabase OTCfgOpenDatabaseManaging Areas OTCfgGetCurrentArea OTCfgOpenArea OTCfgSetCurrentAreaOTCfgCloseArea function result OTCfgBeginAreaModiﬁcationsfunction result OTCfgCommitAreaModiﬁcationsOTCfgAbortAreaModifications returns kCfgErrAreaNotFound OTCfgAbortAreaModiﬁcationsOTCfgIsSameAreaID function resultfunction result OTCfgGetAreaNamefunction result OTCfgSetAreaNameOTCfgGetAreasCount OTCfgGetAreasListfunction result function result that are available.
