Hey John, There is a very simple wrapper class, SharedArray, here: http://www.pressenter.com/~3nelsons/joecode/ it's implemented in the header file, and is easy to use. as long as the destructors are called, everything is cleaned up. use is as simple as typedef struct { ... } MyStruct; MyStruct *MyStructArray = new SharedArray< MyStruct> ( "Name", 100); MyStructArray[1] = ... delete MyStructArray; may not be exact, but close. b\375 ps: I'm forwarding this to [EMAIL PROTECTED] _______________________________________________ Dev mailing list [EMAIL PROTECTED] http://www.trilug.org/mailman/listinfo/dev
