BSEND(3)		   libdill Library Functions		      BSEND(3)

NAME
       bsend - sends data to a socket

SYNOPSIS
	      #include <libdill.h>

	      int bsend(
		  int s,
		  const	void* buf,
		  size_t len,
		  int64_t deadline);

DESCRIPTION
       This  function sends data to a bytestream socket.  It is	a blocking op-
       eration that unblocks only after	all the	data are sent.	 There	is  no
       such  thing  as	partial	send.  If a problem, including timeout,	occurs
       while sending the data error is returned	to the	user  and  the	socket
       cannot be used for sending from that point on.

       s: The socket to	send the data to.

       buf: Buffer to send.

       len: Size of the	buffer,	in bytes.

       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.

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 EBUSY:	The handle is currently	being used by a	different coroutine.

       o ECANCELED: Current coroutine was canceled.

       o ECONNRESET: Broken connection.

       o EINVAL: Invalid argument.

       o ENOTSUP: The handle does not support this operation.

       o EPIPE:	Closed connection.

       o ETIMEDOUT: Deadline was reached.

EXAMPLE
	      int rc = bsend(s,	"ABC", 3, -1);
