<p>File Handles are created by the open, opendir, and create methods and closed by the release and releasedir methods. Multiple file handles may be concurrently open for the same file. Generally, a client will create one file handle per file descriptor, though in some cases multiple file descriptors can share a single file handle.</p>
<p>Note: This data structure is ABI sensitive, new parameters have to be added within padding/padding2 bits and always below existing parameters. </p>
