Correct syntax of bind() function call

• int bind(int, struct sockaddr *, socklen_t*);

• int bind(int *, struct sockaddr *, socklen_t);

• int bind(int, struct sockaddr *, socklen_t);

• int bind(int *, struct sockaddr *, socklen_t*);

• Hard error

• Error due to destination not reachable

• Error due to connection request time out
