IPC_DONE(3)		   libdill Library Functions		   IPC_DONE(3)

NAME
       ipc_done	- half-closes a	IPC connection

SYNOPSIS
	      #include <libdill.h>

	      int ipc_done(
		  int s,
		  int64_t deadline);

DESCRIPTION
       IPC  protocol is	a bytestream protocol for transporting data among pro-
       cesses on the same machine.  It is  an  equivalent  to  POSIX  AF_LOCAL
       sockets.

       This  function  closes  the outbound half of ICP	connection.  This will
       cause the peer to get EPIPE error after it has received all the data.

       s: The IPC connection handle.

       deadline: A point in time when the operation should time	out,  in  mil-
       liseconds.   Use	the now	function to get	your current point in time.  0
       means immediate timeout,	i.e., perform the operation if possible	or re-
       turn  without  blocking	if  not.  -1 means no deadline,	i.e., the call
       will block forever if the operation cannot be performed.

       This function is	not available  if  libdill  is	compiled  with	--dis-
       able-sockets option.

RETURN VALUE
       In case of success the function returns 0.  In case of error it returns
       -1 and sets errno to one	of the values below.

ERRORS
       o EBADF:	Invalid	handle.

       o ECANCELED: Current coroutine was canceled.

       o ENOTSUP: The handle does not support this operation.

       o EPIPE:	The connection was already half-closed.

       o ETIMEDOUT: Deadline was reached.

EXAMPLE
	      int ls = ipc_listen("/tmp/test.ipc", 10);
	      int s = ipc_accept(ls, -1);
	      bsend(s, "ABC", 3, -1);
	      char buf[3];
	      brecv(s, buf, sizeof(buf), -1);
	      ipc_close(s);
	      ipc_close(ls);
