you know that.. in HP-UX..
in sys/pstat.h

struct pst_status {
long pst_idx; /* Index for further pstat() requests */
long pst_uid; /* Real UID */
long pst_pid; /* Process ID */
....
float pst_pctcpu; /* %cpu for this process during p_time
....
}

when, need to get a processor's cpu used %,
we use pst_status.pst_pctcpu..
but i want to know other way.. not use pst_status.pst_pctcpu.
How can I get that??

and what is p_time ??
