I don t suppose there is a way to programmatically enable/disable Valgrind memcheck the way you can with callgrind? (Start/stop instrumentation).
It s painfully, unusably slow (which is okay if the code you want to test starts automatically and you just leave it running), but I can t actually get into the code that s important without clicking a few buttons in the app, which is rendered completely unresponsive. (My code is a plug-in to another app)
Thanks
It s pretty nearly impossible in principle. If valgrind doesn t know the complete history of all your memory, how can it know for sure that something is a leak, or even a reference to invalid memory?
You can t stop/start instrumentation but you can programmatically do incremental leak checks. See http://valgrind.org/docs/manual/mc-manual.html#mc-manual.clientreqs and specifically VALGRIND_DO_LEAK_CHECK, VALGRIND_DO_ADDED_LEAK_CHECK and VALGRIND_DO_CHANGED_LEAK_CHECK.
