class KTimer extends KSynchronizationObject and KTimeableInterruptEvent;
Size : 0x3C bytes
| Offset | Type | Description |
|---|---|---|
| 0x0 | u32 | Pointer to vtable |
| 0x4 | u32 | Reference count |
| 0x8 | u32 | Count of KThreads that sync with this object - number of nodes in the linked list below |
| 0xC | KLinkedListNode* | Pointer to first KLinkedListNode in node list of KThreads that sync with this object |
| 0x10 | KLinkedListNode* | Pointer to last KLinkedListNode in node list of KThreads that sync with this object |
| 0x14 | KTimeableInterruptEvent | Interrupt event (*this) to be used with KTimerAndWDTManager holding its desired time point (relative to the CPU power-on) in CPU ticks (when handling its list of KTimableInterruptEvent instances).
Gets incremented at each interval |
| 0x24 | u8 | Timer is signaled |
| 0x25 | u8 | Timer reset type (one shot, sticky, pulse) |
| 0x26 | u16 | Unknown, probably unused |
| 0x28 | s64 | Interval in nanoseconds |
| 0x30 | s64 | Current value in nanoseconds: current system uptime + user-specified time offset, updated at each interval |
| 0x38 | KProcess* | Owner |
Negative intervals and time offsets are considered null.
