What is struct In_addr?
Likewise, people ask, what is In_addr?
The in_addr structure represents an IPv4 Internet address. When testing return values with inet_pton (using a random IP like 219.225.
Additionally, what is Sockfd? sockfd is the listening socket descriptor. information about incoming connection is stored in. addr which is a pointer to a local struct sockaddr_in. addrlen is set to sizeof(struct sockaddr_in) accept returns a new socket file descriptor to use for.
Similarly, what is Netinet?
The <netinet/in. h> header also defines the IN6ADDR_LOOPBACK_INIT macro. This macro must be constant at compile time and can be used to initialize a variable of type struct in6_addr to the IPv6 loopback address. The <netinet/in.
What is Sin_zero?
As struct sockaddr_in needs to be cast to struct sockaddr it has to be kept the same size, sin_zero is an unused member whose sole purpose is to pad the structure out to 16 bytes (which is the size of sock_addr). This padding size may vary depending on the address family.
