shutdown(3SOCKET)shutdown(3SOCKET)NAME
shutdown - shut down part of a full-duplex connection
SYNOPSIS
cc [ flag... ] file... -lsocket -lnsl [ library... ]
#include <sys/socket.h>
int shutdown(int s, int how);
The shutdown() call shuts down all or part of a full-duplex connection on the socket associated with s. If how is SHUT_RD, further receives
are disallowed. If how is SHUT_WR, further sends are disallowed. If how is SHUT_RDWR, further sends and receives are disallowed.
The how values should be defined constants.
0 is returned if the call succeeds.
-1 is returned if the call fails.
The call succeeds unless one of the following conditions exists:
EBADF The s value is not a valid file descriptor.
ENOMEM Insufficient user memory is available for the operation to complete.
ENOSR Insufficient STREAMS resources are available for the operation to complete.
ENOTCONN The specified socket is not connected.
ENOTSOCK The s value is not a socket.

SHUTDOWN(2) Linux Programmer's Manual SHUTDOWN(2)NAME
shutdown - shut down part of a full-duplex connection
SYNOPSIS
#include <sys/socket.h>
int shutdown(int sockfd, int how);
DESCRIPTION
The shutdown() call causes all or part of a full-duplex connection on the socket associated with sockfd to be shut down. If how is
SHUT_RD, further receptions will be disallowed. If how is SHUT_WR, further transmissions will be disallowed. If how is SHUT_RDWR, further
receptions and transmissions will be disallowed.
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
ERRORS
EBADF sockfd is not a valid descriptor.
ENOTCONN
The specified socket is not connected.
ENOTSOCK
sockfd is a file, not a socket.
CONFORMING TO
POSIX.1-2001, 4.4BSD (the shutdown() function call first appeared in 4.2BSD).
NOTES
The constants SHUT_RD, SHUT_WR, SHUT_RDWR have the value 0, 1, 2, respectively, and are defined in <sys/socket.h> since glibc-2.1.91.
