 SO_LINGER
              Sets or gets the SO_LINGER option.  The argument is a
              linger structure.

                  struct linger {
                      int l_onoff;    /* linger active */
                      int l_linger;   /* how many seconds to linger for */
                  };

              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.  When the socket is closed as part
              of exit(2), it always lingers in the background.
