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 _s_h_u_t_d_o_w_n call causes all or part of a full-duplex con-
     nection on the socket associated with _s to be shut down.  If
     _h_o_w is 0, then further receives will be disallowed.  If _h_o_w
     is 1, then further sends will be disallowed.  If _h_o_w 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.

SEE ALSO
     connect(2), socket(2)
