Size : 0x18 bytes
| Offset | Type | Description |
|---|---|---|
| 0x0 | u32 | Pointer to memory page used for thread local regions for threads owned by a given process |
| 0x4 | KProcess* | Owner process |
| 0x8 | u32 | Number of threads owned by the process |
| 0xC | char[8] | Used to track the usage of thread local regions in the local page. |
| 0x14 | u32 | Zero |
The 8-byte array used to track the regions in use in the page works like so:
Each char is either 1 or 0, and there's one char per thread local region. 0x200 bytes per region * 8 regions is 0x1000 bytes or 1 full page. The chars are set to 1 to indicate the region is unused and 0 to indicate the region is in use.
Processes with more than 8 threads have multiple associated KThreadLocalPages which are linked together with KLinkedListNodes.
