54 | * The system management functions cover disk and power management which |
55 | * are primarily used on portable computers. | |
09ec0018 | 56 | * |
3dfe78b3 MS |
57 | * Disk management involves delaying the write of certain configuration |
58 | * and state files to minimize the number of times the disk has to spin | |
59 | * up. | |
60 | * | |
61 | * Power management support is currently only implemented on MacOS X, but | |
62 | * essentially we use four functions to let the OS know when it is OK to | |
10d09e33 | 63 | * put the system to sleep, typically when we are not in the middle of |
3dfe78b3 MS |
64 | * printing a job. |
65 | * | |
66 | * Once put to sleep, we invalidate all remote printers since it is common | |
67 | * to wake up in a new location/on a new wireless network. | |
