How to use Multiprocessing

[pradeep]

Even i tried with ontimer() function as given in help document of vizard. But i cant get any output from that. It was simply static

import vizact

def Blink_Detection()
print 'inside blink detection function'
............
some process...........
....................

vizact.ontimer2(3,3,Blink_Detection)


but this code does not give any output. Could you please correct me where i should change my mistakes in the code. And also help me to add another function along with my code (say RegionofInterest())

thank you,
