gio.pollable_output_stream.PollableOutputStream is implemented by gio.output_stream.OutputStreams that can be polled for readiness to write. This can be used when interfacing with a non-GIO API that expects UNIX-file-descriptor-style asynchronous I/O rather than GIO-style.
Some classes may implement gio.pollable_output_stream.PollableOutputStream but have only certain instances of that class be pollable. If gio.pollable_output_stream.PollableOutputStream.canPoll returns false, then the behavior of other gio.pollable_output_stream.PollableOutputStream methods is undefined.
