SHUTDOWN(2)	    UNIX Programmer's Manual	      SHUTDOWN(2)


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

SYNOPSIS
     shutdown(s, how)
     int s, how;

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

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.
