\r<h3>FIELDS</h3>
\r<dl>

\rThe total number of free pages in the system.
\r<p>
\r<dt> <var>active_count</var>
\r<dd>
\rThe total number of pages currently in use and pageable.
\r<p>
\r<dt> <var>inactive_count</var>
\r<dd>
\rThe number of inactive pages.
\r<p>
\r<dt> <var>wire_count</var>
\r<dd>
\rThe number of pages that are wired in memory and cannot be paged
\rout.
\r<p>
\r<dt> <var>zero_fill_count</var>
\r<dd>
\rThe number of zero-fill pages.
\r<p>
\r<dt> <var>reactivations</var>
\r<dd>
\rThe number of reactivated pages.
\r<p>
\r<dt> <var>pageins</var>
\r<dd>
\rThe number of requests for pages from a pager (such as the i-node
\rpager).
\r<p>
\r<dt> <var>pageouts</var>
\r<dd>
\rThe number of pages that have been paged out.
\r<p>
\r<dt> <var>faults</var>
\r<dd>
\rThe number of times the <strong>vm_fault</strong> routine has been called.
\r<p>
\r<dt> <var>cow_faults</var>
\r<dd>
\rThe number of copy-on-write faults.
\r<p>
\r<dt> <var>lookups</var>
\r<dd>
\rThe number of object cache lookups.
\r<p>
\r<dt> <var>hits</var>
\r<dd>
\rThe number of object cache hits.
\r</dl>
\r<h3>DESCRIPTION</h3>
\r<p>
\rThe <strong>vm_statistics</strong> structure defines the statistics
\ravailable on the kernel's use of
\rvirtual memory. The statistics record virtual memory usage since
\rthe kernel was booted.
\r<p>
\rFor related information for a specific task, see the <strong>task_basic_info</strong>
\rstructure.
\r<h3>NOTES</h3>
\r<p>
\rThis structure is machine word length specific because of the memory sizes
\rreturned.
