DAQmx Clear Task
Clears the task. Before clearing, this VI stops the task, if necessary, and releases any resources the task reserved. You cannot use a task after you clear it unless you recreate the task.
If you use the DAQmx Create Task VI or the DAQmx Create Virtual Channel VI within a loop, use this VI within the loop after you are finished with the task to avoid allocating unnecessary memory. Refer to Task Creation and Destruction for more information about when to use this VI.

task in is the name of the task to clear. Unlike the task/channels in input on some VIs, you cannot wire a virtual channel to this input. | ||||||

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function runs normally and passes the error in value to error out. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
