NAME
shutdown - shut down socket send and receive operations
SYNOPSIS
#include <sys/socket.h >
int shutdown(int socket , int how );
DESCRIPTION
The shutdown () function shall 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 takes the following arguments:
socket
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.
The shutdown () function disables subsequent send and/or receive
operations on a socket, depending on the value of the
how argument.
RETURN VALUE
Upon successful completion, shutdown () shall return 0; otherwise,
-1 shall be returned and errno set to indicate
the error.
ERRORS
The shutdown () function shall 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
