maximum number of characters in a traditional Ni-DAQ virtual channel and in a NIDAQmx task channel name

What are the maximum number of characters in a traditional NI-DAQ virtual
channel and in a NI-DAQmx task channel name. NI-DAQmx doesn't provide an
warning if the number of characters is exceeded; it crashes instead. Is
this a buffer overflow? I tried counting them but the number is large
enough for this method to be very time consuming and error prone. I'm
trying to customer-proof an application.

Duncan,

This issue has been reported and our developers are looking into the crash. We hope this will be corrected in a future release of the driver. The fundamental limit on a task name is 64 characters, even though you may not be seeing a crash until more characters that this are used.

If you wish to restrict the limit for your customers, I would use 64.

Thanks. I'll use 64 as a limit.
