Idle handles will run the given callback once per loop iteration, right
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.
Despite the name, idle handles will get their callbacks called on every loop iteration, not when the loop is actually “idle”.
Idle handle type.
uv_idle_init(uv_loop_t *loop, uv_idle_t *idle)¶
Initialize the handle. This function always succeeds.
uv_idle_start(uv_idle_t *idle, uv_idle_cb cb)¶
Start the handle with the given callback. This function always succeeds, except when cb is NULL.
0 on success, or UV_EINVAL when cb == NULL.
Stop the handle, the callback will no longer be called. This function always succeeds.
uv_handle_t API functions also apply.
