| 11 | /* This logfile stuff was awful -- it did output to an | |
| 12 | * unbuffered stream. | |
| 13 | * | |
| 14 | * This new version just open the single logfile and writes | |
| 15 | * the record in the stdio buffer. Once that's done, it | |
| 16 | * positions itself at the end of the file (lseek), and | |
| 17 | * writes the buffer out. This could mangle things but | |
| 18 | * it isn't likely. -- ittvax!swatt | |
| 19 | * | |
| 20 | * If the files could be opened with "guaranteed append to end", | |
| 21 | * the lseeks could be removed. | |
| 22 | * Using fseek would be slightly cleaner, | |
| 23 | * but would mangle things slightly more often. | |
