<h2>File Information APIs</h2>
|
|
|
|
<p>See the <a href="../dm/rbal3kickoff.htm">Database file management</a> topic for
|
|
information about traditional file management functions that
|
|
your application uses in creating and accessing data on the server and in ensuring
|
|
the integrity of the data. File management is the part of the operating system that
|
|
controls the storing and accessing of traditional file objects
|
|
(*FILE objects in the QSYS.LIB library) on the server.</p>
