Class FileEndOfFileInformation

java.lang.Object

org.codelibs.jcifs.smb.internal.fscc.FileEndOfFileInformation

All Implemented Interfaces:

Decodable, Encodable, FileInformation

public class FileEndOfFileInformation
extends Object
implements FileInformation, Encodable

File System Control Code (FSCC) structure for File End-of-File Information. Used in SMB2/SMB3 operations to set or query the end-of-file position for a file, effectively controlling file size truncation or extension.
