typedef struct{

.TP 
pages_pagein  
The number of pages swapped into memory.
.TP 
pages_pageout  
The number of pages swapped out of memory (to swap).
.TP 
systime  
The time period over which pages_pagein
and pages_pageout were transferred.
.SH BUGS
Solaris doesn't seem to report accurately. It reports the number
of pages swapped into memory, not necessarily from swap. This
feature isn't deemed entirely reliable.
