Linked List of small secrets in C Language (4)

previous blog "the byte alignment of the little secrets in C language". I will not explain it too much here, if you do not understand it, you can go back and read it again. Through (unsigned long) ( (type *) 0)-> member), we get the offset of the member variable member, and PTR is the pointer to member, because of the different pointer types, we need to first convert (char *) before computation. Therefore, we use PTR to subtract the offset of member to get the pointer of the host struct. This i
