ReplaceIfExists (1 byte): A Boolean (section 2.1.8) value. Set to TRUE to indicate that if the link already exists, it SHOULD be replaced with the new link. Set to FALSE to indicate that the link creation operation MUST fail if the link already exists.
Reserved (3 bytes): This field SHOULD be set to zero by the client and MUST be ignored by the server.
RootDirectory (4 bytes): A 32-bit unsigned integer that contains the file handle for the directory where the link is to be created. For network operations, this value MUST always be zero.
FileNameLength (4 bytes): A 32-bit unsigned integer that contains the length in bytes of the FileName field.
FileName (variable): A sequence of Unicode characters that contains the name to be assigned to the newly created link. When working with the FileName field, the FileNameLength field is used to determine the length of the file name rather than assuming the presence of a trailing null delimiter. If the RootDirectory field is zero, this field MUST specify a full pathname to the link to be created. For network operations, this pathname is relative to the root of the share. If the RootDirectory field is not zero, this field MUST specify a pathname, relative to RootDirectory, for the link name.
