Detailed Description

template<typename T>
struct fairport::disk::fpmap_page< T >

A deprecated allocation system optimized for PMap page searching.

A Free Page Map page has one bit per PMap page, indicating if that PMap page has any slots available. A bit being set indicates there is no space available in that PMap page. No longer used as of Outlook 2007, but still created for backwards compatibility.

The lack of fpmap pages was the reason for the 2GB limit of ANSI pst files (rather than a more intuitive 4GB limit) - the fpmap region in the header only had enough slots to "map" 2GB of space.

Template Parameters:

T	ulonglong for a unicode store, ulong for an ANSI store

Deprecated:
