<br />/*<br /> * Size of the bitmap on each visibility map page, in bytes. There's no<br /> * extra headers, so the
wholepage minus except for the standard page header<br /> * is used for the bitmap.<br /> */<br />#define MAPSIZE
(BLCKSZ- SizeOfPageHeaderData)<br /><br /><br />ISTM that we should MAXALIGN the SizeOfPageHeaderData to compute
MAPSIZE.PageGetContents() works that way and I believe that's the right thing to do.<br /><br />Thanks,<br />Pavan<br
