!!NAME


shutdown - shut down part of a full-duplex connection
!!SYNOPSIS


__#include __


__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 disallowed.
!!RETURN VALUE


On success, zero is returned. On error, -1 is returned, and
''errno'' is set appropriately.
!!ERRORS


__EBADF__


''s'' is not a valid descriptor.


__ENOTSOCK__


''s'' is a file, not a socket.


__ENOTCONN__


The specified socket is not connected.
!!CONFORMING TO


4.4BSD (the __shutdown__ function call first appeared in
4.2BSD).
!!BUGS


The numerical ''how'' flags should be replaced by the
Single Unix-mandated __SHUT_RD__, __SHUT_WR__, and
__SHUT_RDWR__ flags.
!!SEE ALSO


connect(2), socket(2)
