GC.addrOf

core memory GC

Returns the base address of the memory block containing p. This value is useful to determine whether p is an interior pointer, and the result may be passed to routines such as sizeOf which may otherwise fail. If p references memory not originally allocated by this garbage collector, if p is null, or if the garbage collector does not support this operation, null will be returned.

Parameters

Return Value

Type: void*

The base address of the memory block referenced by p or null on error.
