NAME
shutdown - Shuts down socket send and receive operations SYNOPSIS
#include <sys/socket.h> int shutdown ( int socket, int how ); STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: shutdown(): XNS5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. PARAMETERS
Specifies the file descriptor of the socket. Specifies the type of shutdown. Values are: To disable further receive operations To disable further send operations To disable further send operations and receive operations DESCRIPTION
The shutdown() function disables receive and/or send operations on the specified socket. RETURN VALUES
Upon successful completion, a value of 0 (zero) is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error. ERRORS
If the shutdown() function fails, errno may be set to one of the following values: The socket parameter is not valid. The how argument is invalid. Insufficient resources are available in the system to complete the call. The available STREAMS resources were insufficient for the operation to complete. The socket is not connected. The socket parameter refers to a file, not a socket. RELATED INFORMATION

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 operation. The following sections are informative. EXAMPLES
