What is socket AF INET?
What is socket AF INET?
AF_INET is an address family that is used to designate the type of addresses that your socket can communicate with (in this case, Internet Protocol v4 addresses). When you create a socket, you have to specify its address family, and then you can only use addresses of that type with the socket.
What is PF INET?
PF_INET = Packet Format, Internet = IP, TCP/IP or UDP/IP. AF_INET is the address family that is used for the socket you’re creating (in this case an Internet Protocol address).
Why is it called Af_inet?
AF_INET refers to Address from the Internet and it requires a pair of (host, port) where the host can either be a URL of some particular website or its address and the port number is an integer. Hope this answers your question.
Where is Af_inet defined?
The families supported are AF_INET and AF_INET6, which is the Internet domain, and AF_UNIX, which is the local socket domain. These constants are defined in the sys/socket.
How does a raw socket work?
A raw socket is used to receive raw packets. This means packets received at the Ethernet layer will directly pass to the raw socket. Stating it precisely, a raw socket bypasses the normal TCP/IP processing and sends the packets to the specific user application (see Figure 1).
What does binding a socket do?
Binding of a socket is done to address and port in order to receive data on this socket (most cases) or to use this address/port as the source of the data when sending data (for example used with data connections in FTP server).
Where is Sock_dgram defined?
In the Internet domain, the SOCK_DGRAM socket type is implemented on the User Datagram Protocol/Internet Protocol (UDP/IP) protocol. A datagram socket supports the bidirectional flow of data, which is not sequenced, reliable, or unduplicated.
What is struct Hostent?
The hostent structure is used by functions to store information about a given host, such as host name, IPv4 address, and so forth. An application should never attempt to modify this structure or to free any of its components.
