+// Some file types on some platforms seem seekable but in fact are not.
+// The main use of this function is to allow such cases to be detected
+// (IsSeekable() is implemented as wxGetFileKind() == wxFILE_KIND_DISK).
+//
+// This is important for the archive streams, which benefit greatly from
+// being able to seek on a stream, but which will produce corrupt archives
+// if they unknowingly seek on a non-seekable stream.
+//
+// wxFILE_KIND_DISK is a good catch all return value, since other values
+// disable features of the archive streams. Some other value must be returned
+// for a file type that appears seekable but isn't.
+//
+// Known examples:
+// * Pipes on Windows
+// * Files on VMS with a record format other than StreamLF
