public void modify_unix_fd (void* tag, IOCondition new_events)
Updates the event mask to watch for the file descriptor identified by tag.
The tag is the tag returned from [method@GLib.Source.add_unix_fd].
If you want to remove a file descriptor, don’t set its event mask to zero. Instead, call [method@GLib.Source.remove_unix_fd].
This API is only intended to be used by implementations of [struct@GLib.Source]. Do not call this API on a [struct@GLib.Source] that you did not create.
As the name suggests, this function is not available on Windows.
