vm_stat -- show Mach virtual memory statistics SYNOPSIS
vm_stat [[-c count] interval] DESCRIPTION
vm_stat displays Mach virtual memory statistics. If the optional interval is specified, then vm_stat will display the statistics every interval seconds. In this case, each line of output displays the change in each statistic (an interval count of 1 displays the values per second). However, the first line of output following each banner displays the system-wide totals for each statistic. If a count is pro- vided, the command will terminate after count intervals. The following values are displayed: Pages free the total number of free pages in the system. Pages active the total number of pages currently in use and pageable. Pages inactive the total number of pages on the inactive list. Pages speculative the total number of pages on the speculative list. Pages throttled the total number of pages on the throttled list (not wired but not pageable). Pages wired down the total number of pages wired down. That is, pages that cannot be paged out. Pages purgeable the total number of purgeable pages. Translation faults the number of times the "vm_fault" routine has been called. Pages copy-on-write the number of faults that caused a page to be copied (generally caused by copy-on-write faults). Pages zero filled the total number of pages that have been zero-filled on demand. Pages reactivated the total number of pages that have been moved from the inactive list to the active list (reactivated). Pages purged the total number of pages that have been purged. File-backed pages the total number of pages that are file-backed (non-swap) Anonymous pages the total number of pages that are anonymous Uncompressed pages the total number of pages (uncompressed) held within the compressor Pages used by VM compressor: the number of pages used to store compressed VM pages. Pages decompressed the total number of pages that have been decompressed by the VM compressor. Pages compressed the total number of pages that have been compressed by the VM compressor. Pageins the total number of requests for pages from a pager (such as the inode pager). Pageouts the total number of pages that have been paged out. Swapins the total number of compressed pages that have been swapped out to disk. Swapouts the total number of compressed pages that have been swapped back in from disk. If interval is not specified, then vm_stat displays all accumulated statistics along with the page size. Mac OS X August 13, 1997 Mac OS X

Text::PDF::Pages - a PDF pages hierarchical element. Inherits from Text::PDF::Dict DESCRIPTION
A Pages object is the parent to other pages objects or to page objects themselves. METHODS
Text::PDF::Pages->new($pdfs,$parent) This creates a new Pages object. Notice that $parent here is not the file context for the object but the parent pages object for this pages. If we are using this class to create a root node, then $parent should point to the file context, which is identified by not having a Type of Pages. $pdfs is the file object (or objects) in which to create the new Pages object. $p->out_obj($isnew) Tells all the files that this thing is destined for that they should output this object come time to output. If this object has no parent, then it must be the root. So set as the root for the files in question and tell it to be output too. If $isnew is set, then call new_obj rather than out_obj to create as a new object in the file. $p->find_page($pnum) Returns the given page, using the page count values in the pages tree. Pages start at 0. $p->add_page($page, $pnum) Inserts the page before the given $pnum. $pnum can be -ve to count from the END of the document. -1 is after the last page. Likewise $pnum can be greater than the number of pages currently in the document, to append. This method only guarantees to provide a reasonable pages tree if pages are appended or prepended to the document. Pages inserted in the middle of the document may simply be inserted in the appropriate leaf in the pages tree without adding any new branches or leaves. To tidy up such a mess, it is best to call $p->rebuild_tree to rebuild the pages tree into something efficient. $root_pages = $p->rebuild_tree([@pglist]) Rebuilds the pages tree to make a nice balanced tree that conforms to Adobe recommendations. If passed a pglist then the tree is built for that list of pages. No check is made of whether the pglist contains pages. Returns the top of the tree for insertion in the root object. @pglist = $p->get_pages Returns a list of page objects in the document in page order $p->find_prop($key) Searches up through the inheritance tree to find a property. $p->add_font($pdf, $font) Creates or edits the resource dictionary at this level in the hierarchy. If the font is already supported even through the hierarchy, then it is not added. $p->bbox($xmin, $ymin, $xmax, $ymax, [$param]) Specifies the bounding box for this and all child pages. If the values are identical to those inherited then no change is made. $param specifies the attribute name so that other 'bounding box'es can be set with this method. $p->proc_set(@entries) Ensures that the current resource contains all the entries in the proc_sets listed. If necessary it creates a local resource dictionary to achieve this. $p->get_top Returns the top of the pages tree perl v5.8.8 2006-09-09 Text::PDF::Pages(3pm)
