13 * MozRefCountType is Mozilla's reference count type.
15 * We use the same type to represent the refcount of RefCounted objects
16 * as well, in order to be able to use the leak detection facilities
17 * that are implemented by XPCOM.
19 * Note that this type is not in the mozilla namespace so that it is
20 * usable for both C and C++ code.
22 typedef uintptr_t MozRefCountType;
25 * This is the return type for AddRef() and Release() in nsISupports.
26 * IUnknown of COM returns an unsigned long from equivalent functions.
28 * The following ifdef exists to maintain binary compatibility with
29 * IUnknown, the base interface in Microsoft COM.
