HB_IdleWaitNoCPU()

Toggles the mode for CPU usage in Idle wait states.

Syntax

HB_IdleWaitNoCPU( [<lNewMode>] ) --> lOldMode

Arguments

<lNewMode>

This is a logical value determining the mode how a wait state is executed in idle tasks.

Return

The function returns the previous mode for wait states as a logical value.
