- writes).
-
- See the comment in "process_packet()" for an explanation of
- why we do that, and why we don't just use "setvbuf()" to
- make the standard output line-buffered (short version: in
- Windows, "line-buffered" is the same as "fully-buffered",
- and the output buffer is only flushed when it fills up). */

+ stream be flushed to the host environment whenever a newline is
+ written, it just says that, on such a stream, characters "are
+ intended to be transmitted to or from the host environment as a
+ block when a new-line character is encountered".
+
+ The Visual C++ 6.0 C implementation doesn't do what is intended;
+ even if you set a stream to be line-buffered, it still doesn't
+ flush the buffer at the end of every line.
+
+ The whole reason for the "-l" flag in either tcpdump or TShark
+ is to allow the output of a live capture to be piped to a program
+ or script and to have that script see the information for the
+ packet as soon as it's printed, rather than having to wait until
+ a standard I/O buffer fills up.
+
+ So, if the "-l" flag is specified, we flush the standard output
+ at the end of a packet. This will do the right thing if we're
+ printing packet summary lines, and, as we print the entire protocol
+ tree for a single packet without waiting for anything to happen,
+ it should be as good as line-buffered mode if we're printing
+ protocol trees - arguably even better, as it may do fewer

- tcpdump or TShark is to allow the output of a live capture to

- information for the packet as soon as it's printed, rather than
