Adding function to the Idle Task list

Void Idle_run()
{
    Int i;
    UInt hwiKey;

    hwiKey = Hwi_enable();    

    for (i = 0; i < Idle_funcList.length; i++) {
        Idle_funcList.elem[i]();
    }

Looking to add a function to be run continuely in the idle task

how do add to this list both statically and dynamically?

I s there more SYSBIOS docs than the users Manual

Thanks
