* is the short name of the holodeck file, appropriate for window naming, etc. |
49 |
+ |
* The second and third arguments are the file descriptor numbers assigned to |
50 |

* the server's standard output and input, respectively. The stdin and stdout |
51 |
+ |
* of the display process are used for normal communication with the server, |
52 |
+ |
* and are connected to pipes going each way. It is entirely appropriate |
53 |
+ |
* for the display process to borrow the server's stdin and stdout for reading |
54 |
+ |
* and writing user commands from the following list. If the standard input |
55 |
+ |
* is not available for reading, then a descriptor of -1 will be passed. |
56 |
+ |
* The standard output will always be available for writing, though it |
57 |

* may go to /dev/null. |
