.. _idle:
:c:type:`uv_idle_t` --- Idle handle
===================================
Idle handles will run the given callback once per loop iteration, right
before the :c:type:`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".
Data types
----------
.. c:type:: uv_idle_t
Idle handle type.
.. c:type:: void (*uv_idle_cb)(uv_idle_t* handle)
