Function core.memory.GC.addrOf
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.
Prototypes
static inout(void)* addrOf( inout(void)* p ) nothrow; static void* addrOf( void* p ) pure nothrow;
Parameters
| Name | Description |
|---|---|
| p | A pointer to the root or the interior of a valid memory block or to null. |
Returns
The base address of the memory block referenced by p or null on error.
