Function core.memory.GC.sizeOf
Returns the true size of the memory block referenced by p. This value
represents the maximum number of bytes for which a call to realloc may
resize the existing block in place. If p references memory not
originally allocated by this garbage collector, points to the interior
of a memory block, or if p is null, zero will be returned.
Prototypes
static ulong sizeOf( const(void*) p ) nothrow; static ulong sizeOf( void* p ) pure nothrow;
Parameters
| Name | Description |
|---|---|
| p | A pointer to the root of a valid memory block or to null. |
Returns
The size in bytes of the memory block referenced by p or zero on error.
