[sockaddr_in] is a struct in the C programming language that is used to represent an internet socket address for IPv4 addresses. It is defined in the <netinet/in.h> header file.

The [sockaddr_in] struct contains the following fields:

sin_family: specifies the address family, which is typically set to AF_INET for IPv4. sin_port: specifies the port number for the socket address. sin_addr: specifies the IPv4 address of the socket. sin_zero: a padding field that is typically set to all zeros.

The [sockaddr_in] struct is commonly used in network programming to specify the endpoint of a network connection. It is used in conjunction with the socket() system call to create a new socket, and with the bind() system call to bind a socket to a particular IP address and port number.
