     24  * DESCRIPTION
     25  * 	To test the basic functionality of vhangup(2)
     26  *
     27  *
     28  * USAGE:  <for command-line>
     29  *      vhangup02 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
     30  *      where,  -c n : Run n copies concurrently.
     31  *              -i n : Execute test n times.
     32  *              -I x : Execute test for x seconds.
     33  *              -P x : Pause for x seconds between iterations.
     34  *              -t   : Turn on syscall timing.
