* Name: shutdown
*
* Description:
* The shutdown() function will cause all or part of a full-duplex
* connection on the socket associated with the file descriptor socket to
* be shut down.
*
* The shutdown() function disables subsequent send and/or receive
* operations on a socket, depending on the value of the how argument.
*
* Input Parameters:
* sockfd - Specifies the file descriptor of the socket.
* how - Specifies the type of shutdown. The values are as follows:
*
* SHUT_RD - Disables further receive operations.
* SHUT_WR - Disables further send operations.
* SHUT_RDWR - Disables further send and receive operations.
*
* Returned Value:
* Upon successful completion, shutdown() will return 0; otherwise, -1 will
* be returned and errno set to indicate the error.
*
* EBADF - The socket argument is not a valid file descriptor.
* EINVAL - The how argument is invalid.
* ENOTCONN - The socket is not connected.
* ENOTSOCK - The socket argument does not refer to a socket.
* ENOBUFS - Insufficient resources were available in the system to
* perform the operation.
