The following common routines are used in most basic applications.
|DBCHINI||Initializes the DBCAREA, which is shared by an application and most CLIv2 routines. DBCHINI also does the internal initialization of CLIv2.|
Cleans up after an application is finished using Teradata Database.
When DBCHCLN is called and the return code is zero, data structures allocated internally during the calls to CLIv2 routines have been deallocated.
For more information about CLIv2 routines, see Common Routines.
For information about routines that provide information about CLIv2, TDP, or Teradata Database, see CLIv2 Query Routine.
