1890// (IsSeekable() is implemented as wxGetFileKind() == wxFILE_KIND_DISK).
1891//
1892// This is important for the archive streams, which benefit greatly from
1893// being able to seek on a stream, but which will produce corrupt archives
1894// if they unknowingly seek on a non-seekable stream.
1895//
1896// wxFILE_KIND_DISK is a good catch all return value, since other values
1897// disable features of the archive streams. Some other value must be returned
1898// for a file type that appears seekable but isn't.

1900// Known examples:
1901// * Pipes on Windows
1902// * Files on VMS with a record format other than StreamLF
