| 46 * Get the number of seconds the user has been idle. In Unix-world | |
| 47 * this is based on the X Windows usage. In MS Windows this is | |
| 48 * based on keyboard/mouse usage information obtained from the OS. | |
| 49 * In MacOS X, this is based on keyboard/mouse usage information | |
| 50 * obtained from the OS, if configure detected IOKit. Otherwise, | |
| 51 * MacOS X is handled as a case of X Windows. | |
| 52 * | |
| 53 * In Debian bug #271639, jwz says: | |
| 54 * | |
| 55 * Gaim should simply ask xscreensaver how long the user has been idle: | |
| 56 * % xscreensaver-command -time | |
| 57 * XScreenSaver 4.18: screen blanked since Tue Sep 14 14:10:45 2004 | |
| 58 * | |
| 59 * Or you can monitor the _SCREENSAVER_STATUS property on root window #0. | |
| 60 * Element 0 is the status (0, BLANK, LOCK), element 1 is the time_t since | |
| 61 * the last state change, and subsequent elements are which hack is running | |
| 62 * on the various screens: | |
| 63 * % xprop -f _SCREENSAVER_STATUS 32ac -root _SCREENSAVER_STATUS | |
| 64 * _SCREENSAVER_STATUS(INTEGER) = BLANK, 1095196626, 10, 237 | |
| 65 * | |
| 66 * See watch() in xscreensaver/driver/xscreensaver-command.c. | |
