c++ - Forcing the operation system to perform cleanup after a "subroutine" -


i'm writing images-processing program in c++. purpose, have modified third party program (an edge detector) static library use in my program.

it seams original edge detector relied on os clean memory after main function has been executed. unfortunately, after have modified original code, main function became "common" repeatedly called function , no automatic cleaning therefore performed. result huge memory leak every time function called.

i'm not able exhaustively review whole code of detector fix this. i'd therefore ask: in general, there way separate "subroutine" of whole program (in case detector) rest , force os clean after subroutine if stand-alone program? there solution use of threads, example?

thank replies.

if using *nix platform, perhaps fork library call.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
