◆ CONTAINING_RECORD

#define CONTAINING_RECORD ( ptr,
type,
member )
Value:
((type *)((char *)(ptr) - offsetof(type, member)))

This example is using the legacy kernel structures. Usage: CONTAINING_RECORD(ptr, struct, ptr_member) Example: CTX_FRAME* ctxframeptr = 0x1234; // Hypothetical address of the pointer. Thread* threadAssociated = CONTAINING_RECORD(ctxframeptr, Thread, ctx); // Note that ctx is the member name for CTX_FRAME in the Thread struct.
