Queries a file output stream for the given attributes.
This function blocks while querying the stream. For the asynchronous
version of this function, see FileOutputStream.queryInfoAsync.
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.
