Resources and Files

There are three general types of resources that can be attached to a file:

  • User defined resources: Information that you wish to store in the file, such as a file version number, or an infrequently accessed counter. Use resources to store information associated with a file that varies from the type of information stored repetitively in the data records.
  • FairCom defined resources: There is a variety of information that, under certain circumstances, FairCom wishes to store in the file. This can be information relating to IFIL structures, alternate collating sequences, special characters for key padding, and so forth. Usually you do not access this information directly. It is available to a variety of c-tree Plus functions that use it.
  • Third party resources: As other developers create utilities integrating with c-tree Plus, FairCom assigns resource identifiers when necessary.

Resources can be turned off when you create a data or index file. Generally you will not do this, as a number of c-tree features will not be available for this file.
