uv_idle_t — Idle handle

Idle handles will run the given callback once per loop iteration, right before the uv_prepare_t handles.

Note

The notable difference with prepare handles is that when there are active idle handles, the loop will perform a zero timeout poll instead of blocking for i/o.

Warning

Despite the name, idle handles will get their callbacks called on every loop iteration, not when the loop is actually “idle”.
