Hi group,
Could anyone explain to me how do stop and clear functions work, Because after using them I am still able to get the task name and the taskhandle, I did this test:on timer 6602
int32 StopTask()
{ int32 error=0;
char *data;
data=
new char[20];
DAQmxGetTaskName(CO_handle, data, 20);
printf("Before stopping: Taskname=%s, taskhandel=%d\n",data,CO_handle);
error=DAQmxStopTask (CO_handle);
if (error !=0) printf("StopTask error=%d\n",error);
error=DAQmxClearTask(CO_handle);
DAQmxGetTaskName(CO_handle, data, 20);
printf("After clearing: Taskname=%s , taskhandel=%d error=%d\n",data,CO_handle,error);
return error;}
The output was:
Before stopping: Taskname=TIMER , taskhandel=360120584
StopTask error = 0
After clearing: Taskname=TIMER , taskhandel=360120584 error=0
I find this output strange a little bit, I thought clearing the task means destroying it from the memory, but it seams not. This causes problems because in my project I need to stop (and clear) the task and recreate it many times, it sometimes works, but in some cases I got a message "the task is already used" although I had stopped and cleared it.
Best regards
Amna
