you could probably use operator new overloading, but i'm not sure. nev=

overloaded one.

Or you could do this:

template<typename T>
T* new_thread(Func_type f, int state)
{
T* ret = NULL;
try {
ret = new Thread(f, state);
}
catch (...) {
// do something, or not
}

return ret;

}

Or I think it makes sense to get new_thread as static function-member of
Thread class say Thread::create. I'd prefer this, cause it number of
reduces global scoped free functions.

Yeah, I kind of switched gears mid-stream -- I started with a generic
template to deal with any type of create and then halfway through
switched to "Thread" specific -- mainly because I couldn't remember
the syntax for variadic templates.

My intent was to provide a generic "new" for OP that catches all
exceptions, including those thrown by the constructor.
