|
|
<p>In addition to the Integrated File System commands and menus, i5/OS provides APIs that
|
|
enable ILE C for iSeries™ programs to perform functions on files and directories
|
|
in all file systems. The Integrated File System APIs are very useful for integrating the iSeries database with NetWare Enhanced Integration data. You can find information about ILE and ILE
|
|
C for iSeries in the book <a href="../books/sc415606.pdf" target="_blank">ILE Concepts,
|
|
SC41-5606</a>
|
|
<img src="wbpdf.gif" alt="Link to PDF" />.</p>
|
|
<p>When you use Integrated File System APIs on the QNetWare file system, you need to know that these C language
|
|
functions are not supported on the QNetWare file system: </p>
