MemoryBlockDescriptor [constructor] | Constructors |
operator= | Assign to this memory block descriptor the value of the specified rhs descriptor and return a reference to this modifiable descriptor. |
address | Return the address of the modifiable memory block described by this object, or 0 if this is a null descriptor. |
