Wireshark · Ethereal-dev: [Ethereal-dev] what does sync_mode mean??

["Li Haijiang" <lhjiang@xxxxxx>]

I found the struct capture_options have the item of sync_mode in the capture.h.
but i don't know when it is in the sync_mode or in the normally mode and then code
in the capture.c file have two different function to call.
-----------the code in the capture.c
if (capture_opts.sync_mode) {	
    /* sync mode: do the capture in a child process */
    return sync_pipe_do_capture(is_tempfile);
    /* capture is still running */
  } else {
    /* normal mode: do the capture synchronously */
    return normal_do_capture(is_tempfile);
    /* capture is finished here */
  }
------------
