The sockaddr structure is defined as follows:
struct sockaddr {
unsigned short sa_family; // Address family (e.g. AF_INET)
char sa_data[14]; // Protocol-specific address data
};
The actual structure passed for the addr argument in a function call will depend on the specific address family being used, such as AF_INET for IPv4 or AF_INET6 for IPv6. The sa_family member indicates the address family being used, and the remaining sa_data array holds protocol-specific address data.
