IviSwtchSoftwareTrigger Behavior Model

The IviSwtchSoftwareTrigger extension group follows the behavior model of the IviSwtchScanner extension group. If the IVISWTCH_ATTR_TRIGGER_INPUT is set to IVISWTCH_VAL_SOFTWARE_TRIG, the switch exits the wait-for-trigger state only after the IviSwtch_SendSoftwareTrigger function executes.
