Re: sending data on a socket followed by a close

[Stephen Samuel <samuel@bcgreen.com>]

Rather than using close, try calling shutdown (2)...
(dunno if it will work).

If that doesn't work, then use the socket option  SO_LINGER

SO_LINGER     When enabled, a close(2) or shutdown(2) will  not  return
               until all  queued  messages for the socket have been
               successfully sent or the linger timeout has  been  reached.
               Otherwise,  the  call returns  immediately  and the closing
               is done in the background.

man 7 socket
