ILE C/C++ Programmer's Guide


iSeries Data Management Files

An ILE C stream file or record file is the same as an iSeries Data Management file. System files are also called file objects. Each iSeries Data Management file or file object is differentiated and categorized by information that is stored within it. Each file has its own set of unique characteristics, which determine how the file can be used and what capabilities it provides. This information is called the file description.

The file description also contains the file's characteristics, details on how the data associated with the file is organized into records, and how the fields are organized within these records. Whenever a file is processed, the operating system uses the file description. Data is created and accessed on the system through file objects.
