g_source_add_unix_fd (
  GSource* source,
  gint fd,
  GIOCondition events
)

Monitors fd for the IO events in events.

The tag returned by this function can be used to remove or modify the monitoring of the fd using g_source_remove_unix_fd() or g_source_modify_unix_fd().

It is not necessary to remove the fd before destroying the source; it will be cleaned up automatically.

This API is only intended to be used by implementations of GSource. Do not call this API on a GSource that you did not create.

As the name suggests, this function is not available on Windows.
