SHUTDOWN(2)			     BSD System Calls Manual			      SHUTDOWN(2)

NAME
     shutdown -- shut down part of a full-duplex connection

SYNOPSIS
     #include <sys/socket.h>

     int
     shutdown(int s, int how);

DESCRIPTION
     The shutdown() call causes all or part of a full-duplex connection on the socket associated
     with s to be shut down.  If how is 0, further receives will be disallowed.  If how is 1,
     further sends will be disallowed.	If how is 2, further sends and receives will be disal-
     lowed.

DIAGNOSTICS
     A 0 is returned if the call succeeds, -1 if it fails.

ERRORS
     The call succeeds unless:

     [EBADF]		S is not a valid descriptor.

     [ENOTSOCK] 	S is a file, not a socket.

     [ENOTCONN] 	The specified socket is not connected.

SEE ALSO
     connect(2), socket(2)

HISTORY
     The shutdown() function call appeared in 4.2BSD.
