How to initialize variables for struct sockaddr_in

Question

When I initialize variables, I do bellow.

int i = 0;
char *myText = NULL;

Then, haw can I initialize struct sockaddr_in type variables?

struct sockaddr_in addr = ?;

Answer 1

If you want to set all fields to zero in a declaration, no matter the structure, then do e.g.

struct some_struct var = { 0 };

Answer 2

you can use memset

Lets say you want to initialize the entire addr structure variable to 0, you can do it as follows.

memset(&addr, 0, sizeof(struct sockaddr_in));

If you want to initialize it using different values you can refer to the example here
