The SCPreferencesPathXXX() APIs make certain assumptions about the layout of the preferences data. These APIs view the data as a collection of dictionaries of key/value pairs and an associated path name. The root path ("/") identifies the top-level dictionary. Additional path components specify the keys for sub-dictionaries. For example, the following dictionary can be accessed via two paths. The root ("/") path would return a dictionary with all keys and values. The path "/path1" would only return the dictionary with the "key3" and "key4" properties. <PRE> <BR> <dict> <BR> <key>key1</key> <BR> <string>val1</string> <BR> <key>key2</key> <BR> <string>val2</string> <BR> <key>path1</key> <BR> <dict> <BR> <key>key3</key> <BR> <string>val3</string> <BR> <key>key4</key> <BR> <string>val4</string> <BR> </dict> <BR> </dict> </PRE> Each dictionary can also include the kSCResvLink key. The value associated with this key is interpreted as a "link" to another path. If this key is present, a call to the SCPreferencesPathGetValue() API will return the dictionary specified by the link. The APIs provided by this framework communicate with the "configd" daemon for any tasks requiring synchronization and/or notification. */ __BEGIN_DECLS /*! @function SCPreferencesPathCreateUniqueChild @discussion Creates a new path component within the dictionary hierarchy. @param session The SCPreferencesRef handle that should be used to communicate with the APIs. @param prefix A string that represents the parent path. @result A string representing the new (unique) child path; NULL if the specified path does not exist. */ CFStringRef SCPreferencesPathCreateUniqueChild ( SCPreferencesRef session, CFStringRef prefix ); /*! @function SCPreferencesPathGetValue @discussion Returns the dictionary associated with the specified path. @param session The SCPreferencesRef handle that should be used to communicate with the APIs. @param path A string that represents the path to be returned. @result The dictionary associated with the specified path; NULL if the path does not exist. */ CFDictionaryRef SCPreferencesPathGetValue ( SCPreferencesRef session, CFStringRef path ); /*! @function SCPreferencesPathGetLink @discussion Returns the link (if one exists) associated with the specified path. @param session The SCPreferencesRef handle that should be used to communicate with the APIs. @param path A string that represents the path to be returned. @result The dictionary associated with the specified path; NULL if the path is not a link or does not exist. */ CFStringRef SCPreferencesPathGetLink ( SCPreferencesRef session, CFStringRef path ); /*! @function SCPreferencesPathSetValue @discussion Associates a dictionary with the specified path. @param session The SCPreferencesRef handle that should be used to communicate with the APIs. @param path A string that represents the path to be updated. @param value A dictionary that represents the data to be stored at the specified path. @result A boolean indicating the success (or failure) of the call. */ Boolean SCPreferencesPathSetValue ( SCPreferencesRef session, CFStringRef path, CFDictionaryRef value ); /*! @function SCPreferencesPathSetLink @discussion Associates a link to a second dictionary at the specified path. @param session The SCPreferencesRef handle that should be used to communicate with the APIs. @param path A string that represents the path to be updated. @param link A string that represents the link to be stored at the specified path. @result A boolean indicating the success (or failure) of the call. */ Boolean SCPreferencesPathSetLink ( SCPreferencesRef session, CFStringRef path, CFStringRef link ); /*! @function SCPreferencesPathRemoveValue @discussion Removes the data associated with the specified path. @param session The SCPreferencesRef handle that should be used to communicate with the APIs. @param path A string that represents the path to be returned. @result A boolean indicating the success (or failure) of the call. */ Boolean SCPreferencesPathRemoveValue ( SCPreferencesRef session, CFStringRef path ); __END_DECLS #endif /* _SCPREFERENCESPATH_H */
