Is there a problem new'ing a bunch of objects from one thread and
deleting them in another? I do something like:
void operator()(T* p)
if (ptr != 0)
ptr = 0;
typedef vector<classofpointers*> vecptrs;
// use some platform specific API to wait until
for_each(myptrs.begin(), myptrs.end(), GenericPointerDeleter());
DWORD WINAPI threadcallbackroutine(LPVOID param)
vecptrs* my_ptrs = static_cast<vecptrs*>(param);
I have vastly simplified what is essentially happening in my

I don't have access to Windows, but I believe your code is fine. The
C++ committee is interested in C++0X have a multi-threaded memory model
which will probably be based on current practice today. And as far as I
know, current practice is that transferring memory ownership across
thread boundaries is fine.
