Gio.PollableInputStream.prototype.create_source

function create_source(cancellable: Gio.Cancellable): GLib.Source {
    // Gjs wrapper for g_pollable_input_stream_create_source()
}
  

Creates a GLib.Source that triggers when stream can be read, or cancellable is triggered or an error occurs. The callback on the source is of the Gio.PollableSourceFunc type.

As with Gio.PollableInputStream.prototype.is_readable, it is possible that the stream may not actually be readable even after the source triggers, so you should use Gio.PollableInputStream.prototype.read_nonblocking rather than Gio.InputStream.prototype.read from the callback.
