GFileIOStream provides io streams that both read and write to the same
file handle.

GFileIOStream implements '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 'GI.Gio.Objects.FileIOStream.FileIOStream' operations
and the implementation of 'GI.Gio.Interfaces.Seekable.Seekable' just call into the same operations
on the output stream.

Queries a file io stream for the given /@attributes@/.
This function blocks while querying the stream. For the asynchronous
version of this function, see 'GI.Gio.Objects.FileIOStream.fileIOStreamQueryInfoAsync'.
While the stream is blocked, the stream will set the pending flag
internally, and any other operations on the stream will fail with
'GI.Gio.Enums.IOErrorEnumPending'.

Can fail if the stream was already closed (with /@error@/ being set to
'GI.Gio.Enums.IOErrorEnumClosed'), the stream has pending operations (with /@error@/ being
set to 'GI.Gio.Enums.IOErrorEnumPending'), or if querying info is not supported for
the stream\'s interface (with /@error@/ being set to 'GI.Gio.Enums.IOErrorEnumNotSupported'). I
all cases of failure, 'Nothing' will be returned.

If /@cancellable@/ is not 'Nothing', then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error 'GI.Gio.Enums.IOErrorEnumCancelled' will be set, and 'Nothing' will
be returned.
