addr Points to a structure of type sockaddr_in where accept()
stores the address of the connected socket. The structure
sockaddr_in is defined in the file and has the following
format:
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 Points to an integer equal to 16, which is the size in bytes of
the sockaddr_in structure.
If this call succeeds, it returns a non-negative integer that is a descriptor for the
accepted socket. It returns -1 on error.
