c++ - Does Release call on an Interface ensure that the COM Component is distroyed -

i working on issue see intermittent crashes happening @ customer site, while code review, found have written code in destructor free memory etc. question when destruct-or gets called.

does called when client call's release on interface. or how free resources consumed interface or when supposed free resources.

i know when call relase returns "0" com calls dllcangetunloadnow , dll unloaded , freeing memory?

can clarify

regards tom

typically implementing object's destructor called release if reference count has reached zero. performed implementing object's implementation of release.

so, typical implementation of release looks this:

ifacemethodimp_(ulong) release() {     ulong cref = interlockeddecrement(&_cref);      if (!cref)         delete this;     return cref; }
