addr Points to a sockaddr_in structure that contains the address of the
foreign socket. The structure sockaddr_in is defined as follows:
struct sockaddr_in {
short sin_family; /* must be AF_INET */
unsigned short sin_port; /* 16-bit port number */
struct in_addr sin_addr; /* 32-bit IP address */
char sin_zero[8]; /* must be 0 */
};
This structure cannot be packed.
addrlen Specifies the size in bytes of the sockaddr_in structure and must
be 16.
This system call returns 0 if successful, otherwise it returns -1.
