Yes! Thank you Google. Not quite a pointer to the constructor that I bloody should be able to get (the resultant assembly code calls it directly like any other function, so why can't I?), but good enough.class STUPID {
public:
static void *ConstructoryEnough(void *pos) {return new(pos) STUPID;}
};
typedef void* (*CONSTRUCTORPOINTER)(void*);
void *ConstructMeOneOfThese(CONSTRUCTORPOINTER p,void *space) {
p(space);
}
int main() {
char buffer[sizeof(STUPID)];
void *(*pconstructor)(void*)=STUPID::ConstructoryEnough;
ConstructMeOneOfThese(pconstructor,buffer); //constructor is called using only a pointer and an allocated space, yay
((STUPID*)buffer)->~STUPID(); //destructor called directly, but could be pointerised the same way
} Hidden behind that block of code is a really great story about some funny things that happened to me when I went to the shops the other day, and also some pictures of really great things I saw - amusing and pornographic things. See what C++ does? You've all missed out on that fantastic material, and it's all because of C++ engaging in coverups.
