class [[KProcess]] extends [[KSynchronizationObject]] and [[KSendableInterruptEvent]];
Size : 0x260 bytes
Size : 0x270 (N3DS) / 0x268 bytes (O3DS post 8.x) / 0x260 bytes (O3DS pre 8.x). 0x4D8 bytes on ARM9.
The only field that changed is the [[KProcessHwInfo]] member instance. The definition of KProcess remain identical in all cases.
The listed offsets are N3DS-only.
