BCB kako napuniti windows strukturu nulama

Kako napuniti win API strukturu sa nulama
na primer:

OVERLAPPED *owl;
memcpy(owl,0, sizeof(OVERLAPPED)); // run time error

To nije Windows struktura, nego neinicijalizovani pointer u momentu kad ga punish nulama, zato i puca.

Da si uradio ovako :

OVERLAPPED owl; // nije pointer!
memcpy(&owl,0, sizeof(OVERLAPPED));

radilo bi bez problema. Ili eventualno da dinamichki alocirash tu strukturu.

Code:

OVERLAPPED *owl = new OVERLAPPED;
memcpy(owl,0, sizeof(OVERLAPPED));

ili

Code:

OVERLAPPED *owl = (OVERLAPPED *)malloc(sizeof(OVERLAPPED));
memcpy(owl,0, sizeof(OVERLAPPED));

nezaboravi kad ti vise ta struktura nebude trebala napravit

Code:
free(owl);

ili

Code:
delete owl;
