-- GFileIOStream provides io streams that both read and write to the same
-- file handle.
-- 
-- GFileIOStream implements t'GI.Gio.Interfaces.Seekable.Seekable', which allows the io
-- stream to jump to arbitrary positions in the file and to truncate
-- the file, provided the filesystem of the file supports these
-- operations.
-- 
-- To find the position of a file io stream, use
-- 'GI.Gio.Interfaces.Seekable.seekableTell'.
-- 
-- To find out if a file io stream supports seeking, use 'GI.Gio.Interfaces.Seekable.seekableCanSeek'.
-- To position a file io stream, use 'GI.Gio.Interfaces.Seekable.seekableSeek'.
-- To find out if a file io stream supports truncating, use
-- 'GI.Gio.Interfaces.Seekable.seekableCanTruncate'. To truncate a file io
-- stream, use 'GI.Gio.Interfaces.Seekable.seekableTruncate'.
-- 
-- The default implementation of all the t'GI.Gio.Objects.FileIOStream.FileIOStream' operations
-- and the implementation of t'GI.Gio.Interfaces.Seekable.Seekable' just call into the same operations
-- on the output stream.
