recvfrom()

This is used to receive a message from a connection-mode or connectionless-mode socket. Here it its syntax:

ssize_t recvfrom(int fdsock, void *buffer, size_t length, int flags, struct sockaddr *address, socklen_t *address_len);

Here, we need to address the following:

• fdsock: Represents the file descriptor of the socket.
• buffer: Represents the buffer where the message is stored.
• length: Represents the number of bytes of the buffer that are pointed to by the buffer parameter.
• flags: Represents the type of message that's received.
• address: Represents the sockaddr structure in which the sending address is stored. The length and format of the address depend on the address family of the socket.
• address_len: Represents the length of ...
