Include files for Db2 API applications

The include files that are intended to be used in your C, C++, COBOL and FORTRAN applications to call Db2 APIs are described in the following list:

C and C++ include files

DB2APIDF (db2ApiDf.h): This file defines structures, constants, and prototypes for almost all Db2 APIs whose names start with 'db2'.
DB2AUCFG (db2AuCfg.h): This file defines structures, constants, and prototypes for the Db2 APIs, db2AutoConfig and db2AutoConfigFreeMemory.
DB2SECPLUGIN (db2secPlugin.h): This file defines structures, constants, and prototypes for APIs used to develop customized security plug-ins for authentication and group membership lookup purposes.
SQL (sql.h): This file includes language-specific prototypes for the binder, precompiler, and error message retrieval APIs. It also defines system constants.
SQLAPREP (sqlaprep.h): This file contains definitions required to write your own precompiler.
SQLENV (sqlenv.h): This file defines language-specific calls for the database environment APIs, and the structures, constants, and return codes for those interfaces.
SQLMON (sqlmon.h): This file defines language-specific calls for the database system monitor APIs, and the structures, constants, and return codes for those interfaces.
SQLUTIL (sqlutil.h): This file defines the language-specific calls for the utility APIs, and the structures, constants, and codes required for those interfaces.
SQLUVEND (sqluvend.h): This file defines structures, constants, and prototypes for the APIs to be used by the storage management vendors.
SQLXA (sqlxa.h): This file contains function prototypes and constants used by applications that use the X/Open XA Interface.

COBOL include files

SQL (sql.cbl): This file includes language-specific prototypes for the binder, precompiler, and error message retrieval APIs. It also defines system constants.
SQLAPREP (sqlaprep.cbl): This file contains definitions required to write your own precompiler.
SQLENV (sqlenv.cbl): This file defines language-specific calls for the database environment APIs, and the structures, constants, and return codes for those interfaces.
SQLMON (sqlmon.cbl): This file defines language-specific calls for the database system monitor APIs, and the structures, constants, and return codes for those interfaces.
SQLMONCT (sqlmonct.cbl): This file contains constant definitions and local data structure definitions required to call the Database System Monitor APIs.
SQLUTIL (sqlutil.cbl): This file defines the language-specific calls for the utility APIs, and the structures, constants, and codes required for those interfaces.

FORTRAN include files

SQL (sql.f): This file includes language-specific prototypes for the binder, precompiler, and error message retrieval APIs. It also defines system constants.
SQLAPREP (sqlaprep.f): This file contains definitions required to write your own precompiler.
SQLENV (sqlenv.f): This file defines language-specific calls for the database environment APIs, and the structures, constants, and return codes for those interfaces.
SQLMON (sqlmon.f): This file defines language-specific calls for the database system monitor APIs, and the structures, constants, and return codes for those interfaces.
SQLUTIL (sqlutil.f): This file defines the language-specific calls for the utility APIs, and the structures, constants, and codes required for those interfaces.
