DataStore Library | 
2 Creating a DataStore The DataStore Library provides a system for storing and manipulating collections of structured data. Data reside in numbered records with type-defined fields; each collection of records is called a datastore. An application can access different datastores simultaneously; similarly, multiple applications can access a single datastore concurrently.
The DataStore Manager manages synchronization by issuing "session tokens" whenever an application opens (or creates) a datastore. An application can have multiple sessions, each identified by a unique token.
The DataStore Library contains routines for creating and accessing data on the file level, record level, and field level. All the routines return an error value which is useful for error checking. For a full list of routines and their parameter lists, see the C Reference Book (routines are listed alphabetically and all DataStore routines begin with "DataStore").
