int32 DAQmxStopTask (TaskHandle taskHandle);

Purpose

Stops the task and returns it to the state it was in before you called DAQmxStartTask or called an NI-DAQmx Write function with autoStart set to TRUE.

If you do not call DAQmxStartTask and DAQmxStopTask when you call NI-DAQmx Read functions or NI-DAQmx Write functions multiple times, such as in a loop, the task starts and stops repeatedly. Starting and stopping a task repeatedly reduces the performance of the application.

Return Value
