Closes the specified session and frees reserved resources. If the session is running, it is first aborted.

To prevent generating unwanted signal glitches between initializing and closing sessions, no front panel terminals or channels are tristated by the niHSDIO Close VI. The terminals and channels are all left driving whatever voltage they would have been driving had you used theniHSDIO Abort VI. Use the niHSDIO Reset VI before the niHSDIO Close VI if you want to tristate all terminals and channels before closing your session.
