>SHUTDOWN(2)                   System Calls Manual                  SHUTDOWN(2)
 
NAME
     shutdown - shut down part of a full-duplex connection
 
SYNOPSIS
     #include &lt;sys/types.h&#62;
     #include &lt;sys/socket.h&#62;
 
     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 SHUT_RD, further
     receives will be disallowed.  If how is SHUT_WR, further sends will be
     disallowed.  If how is SHUT_RDWR, further sends and receives will be dis-
     allowed.
 
RETURN VALUES
     A 0 is returned if the call succeeds, -1 if it fails.
 
ERRORS
     The call succeeds unless:
 
     [EINVAL]           how is not SHUT_RD, SHUT_WR, or SHUT_RDWR.
 
     [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.  The how arguments used
     to be simply 0, 1, and 2, but now have named values as specified by
     X/Open Portability Guide Issue 4 (``XPG4'').
 
BSD                              June 4, 1993                              BSD
