-// Return the type of an open file
-//
-// 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
