How do I pass in the skt member of 'struct cam' to function sock_create() which has arg that requires a pointer to a pointer?Code:// sock_create signature ... int sock_create(int family, int type, int protocol, struct socket **res); struct bam { union am *lay; }; struct cam { struct socket *skt; };
Code:struct bam *bm; struct cam *cm; // ... cm = (struct cam *)bm->lay; // cm->skt wrong here, but not sure how to pass in. ret = sock_create(AF_INET, SOCK_STREAM, IPPROTO_TCP, cm->skt);
Take the address of the pointer

I understand that's what I need to do, but confused on the syntax ... &(cm->skt)

Yep, though you don't need the parentheses.
It is too clear and so it is hard to see.
A dunce once searched for fire with a lighted lantern.
Had he known what fire was,
He could have cooked his rice much sooner.
