IPC_ACCEPT(3)		   libdill Library Functions		 IPC_ACCEPT(3)

NAME
       ipc_accept - accepts an incoming	IPC connection

SYNOPSIS
	      #include <libdill.h>

	      int ipc_accept(
		  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 accepts an	incoming IPC connection.

       s: Socket created by ipc_listen.

       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.

       The socket can be cleanly shut down using ipc_close function.

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

RETURN VALUE
       In case of success the function returns handle of the  new  connection.
       In  case	of error it returns -1 and sets	errno to one of	the values be-
       low.

ERRORS
       o EBADF:	Invalid	handle.

       o ECANCELED: Current coroutine was canceled.

       o EMFILE: The maximum number of file descriptors	in the process are al-
	 ready open.

       o ENFILE:  The maximum number of	file descriptors in the	system are al-
	 ready open.

       o ENOMEM: Not enough memory.

       o ENOTSUP: The handle does not support this operation.

       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);
