50 + * The display process is started with three arguments.  The first argument
51 + * is the short name of the holodeck file, appropriate for window naming, etc.
52 + * The second and third arguments are the file descriptor numbers assigned to
53 + * the server's standard output and input, respectively.  The stdin and stdout
54 + * of the display process are used for normal communication with the server,
55 + * and are connected to pipes going each way.  It is entirely appropriate
56 + * for the display process to borrow the server's stdin and stdout for reading
57 + * and writing user commands from the list in rhdriver.h.  If standard input
58 + * is not available for reading, then a descriptor of -1 will be passed.
59 + * The standard output will always be available for writing, though it
60 + * may go to /dev/null.
