NAME

       shutdown - shut down socket send and receive operations

SYNOPSIS

       cc [ flag ... ] file ... -lxnet [ library ... ]
       #include <sys/socket.h>

       int shutdown(int socket, int how);

DESCRIPTION

       The shutdown() function disables subsequent send() and receive() operations on a socket, depending on the value of the how argument.

PARAMETERS

       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.

       socket	 Specifies the file descriptor of the socket.

RETURN VALUES

       Upon successful completion, shutdown() returns 0.  Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The shutdown() function will fail if:

       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.

       The shutdown() function may fail if:

       ENOBUFS	  Insufficient resources were available in the system to perform the operation.

       ENOSR	  There were insufficient STREAMS resources available for the operation to complete.

NAME

       getpeername - get the name of the peer socket

SYNOPSIS

       cc [ flag ... ] file ... -lxnet [ library ... ]
       #include <sys/socket.h>

       int getpeername(int socket, struct sockaddr *restrict address, socklen_t *restrict address_len);

DESCRIPTION

       The  getpeername() function retrieves the peer address of the specified socket, stores this address in the sockaddr structure pointed to by
       the address argument, and stores the length of this address in the object pointed to by the address_len argument.

       If the actual length of the address is greater than the length of the supplied sockaddr structure, the stored address will be truncated.

       If the protocol permits connections by unbound clients, and the peer is not bound, then the value  stored  in  the  object  pointed  to	by
       address is unspecified.

RETURN VALUES

       Upon successful completion, 0 is returned.  Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The getpeername() function will fail if:

       EBADF	       The socket argument is not a valid file descriptor.

       EFAULT	       The  address or	address_len parameter can not be accessed or written.

       EINVAL	       The socket has been shut down.

       ENOTCONN        The socket is not connected or otherwise has not had the peer prespecified.

       ENOTSOCK        The socket argument does not refer to a socket.

       EOPNOTSUPP      The operation is not supported for the socket protocol.

       The getpeername() function may fail if:

       ENOBUFS	       Insufficient resources were available in the system to complete the call.

       ENOSR	       There were insufficient STREAMS resources available for the operation to complete.
