source: osgVisual/include/extLink/dataIO_extLink.h @ 94

Last change on this file since 94 was 88, checked in by Torben Dannhauer, 14 years ago

Moved memory leak detection from source file to headerfile. Its still in the class but at least not in the source file.

The leak detection works, but the false positives are not stopped.
Use Linux/Valgrind? to make your final leak detection beyond the easy first approach in MSVC
