Abstract:

????This?module?contains?the?code?that?implements?the?general?purpose?sample
????file?system?filter?driver.

????As?of?the?Windows?XP?SP1?IFS?Kit?version?of?this?sample?and?later?this
????sample?can?be?built?for?each?build?environment?released?with?the?IFS?Kit
????with?no?additional?modifications.??To?provide?this?capability?additional
????compile-time?logic?was?added?--?see?the?‘#if?WINVER‘?locations.??Comments
????tagged?with?the?‘VERSION?NOTE‘?header?have?also?been?added?as?appropriate?to
????describe?how?the?logic?must?change?between?versions.

????If?this?sample?is?built?in?the?Windows?XP?environment?or?later?it?will?run
????on?Windows?2000?or?later.??This?is?done?by?dynamically?loading?the?routines
????that?are?only?available?on?Windows?XP?or?later?and?making?run-time?decisions
????to?determine?what?code?to?execute.??Comments?tagged?with?‘MULTIVERISON?NOTE‘
