Include Files

The include files that are provided with the runtime library contain macro and constant definitions, type definitions, and function declarations. Some functions require definitions and declarations from include files to work properly. The inclusion of files is optional, as long as the necessary statements from the files are coded directly into the source.

This section describes each include file, explains its contents, and lists the functions that are declared in the file.

The QSYSINC (system openness includes) library must be installed on your operating system. QSYSINC contains include files useful for C/C++ users, such as system API, Dynamic Screen Manager (DSM), and ILE header files. The QSYSINC library contains header files that include the prototypes and templates for the machine interface (MI) built-ins and the ILE C/C++ MI functions. See the ILE C/C++ for AS/400 MI Library Reference for more information about these header files.
