SHUTDOWN(2)                                                        SHUTDOWN(2)


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

SYNOPSIS
     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, 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.

SEE ALSO
     connect(2), socket(2)

NOTE
     ABI-compliant versions of the above call can be obtained from
     libsocket.so.
