+ |
* 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. |
