1898// (IsSeekable() is implemented as wxGetFileKind() == wxFILE_KIND_DISK).
1899//
1900// This is important for the archive streams, which benefit greatly from
1901// being able to seek on a stream, but which will produce corrupt archives
1902// if they unknowingly seek on a non-seekable stream.
1903//
1904// wxFILE_KIND_DISK is a good catch all return value, since other values
1905// disable features of the archive streams. Some other value must be returned
1906// for a file type that appears seekable but isn't.

1908// Known examples:
1909// * Pipes on Windows
1910// * Files on VMS with a record format other than StreamLF
