pipe instead of stdin. Add an argument (currently the parent PID) back to the "-Z" flag and use it to construct the pipe name. This lets us pass the parent's stdin handle to dumpcap, which lets us capture from stdin on Windows. Add a comment about checking for the parent process. In capture_loop.c, remove the wait_forever argument from cap_pipe_select() since it was always FALSE. Set the timeout under Windows to 250 ms instead of 250000 ms. svn path=/trunk/; revision=23279
