Queries a file output stream for the given @attributes.
This function blocks while querying the stream. For the asynchronous
version of this function, see g_file_output_stream_query_info_async().
While the stream is blocked, the stream will set the pending flag
internally, and any other operations on the stream will fail with
%G_IO_ERROR_PENDING.
Can fail if the stream was already closed (with @error being set to
%G_IO_ERROR_CLOSED), the stream has pending operations (with @error being
set to %G_IO_ERROR_PENDING), or if querying info is not supported for
the stream's interface (with @error being set to %G_IO_ERROR_NOT_SUPPORTED). In
all cases of failure, %NULL will be returned.
If @cancellable is not %NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error %G_IO_ERROR_CANCELLED will be set, and %NULL will
be returned.
