1905// (IsSeekable() is implemented as wxGetFileKind() == wxFILE_KIND_DISK).
1906//
1907// This is important for the archive streams, which benefit greatly from
1908// being able to seek on a stream, but which will produce corrupt archives
1909// if they unknowingly seek on a non-seekable stream.
1910//

1912// disable features of the archive streams. Some other value must be returned
1913// for a file type that appears seekable but isn't.

1915// Known examples:
1916// * Pipes on Windows
1917// * Files on VMS with a record format other than StreamLF
