DESCRIPTION
       The  _lwp_info()  function  fills  the  lwpinfo structure pointed to by	buffer with time-

	 timestruc_t   lwp_utime;
	 timestruc_t   lwp_stime;

       The lwp_utime member is the CPU time used while executing instructions in the  user  space
       of the calling LWP.

       The lwp_stime member is the CPU time used by the system on behalf of the calling LWP.
