+Memory
+=============
+
+size_t and unsigned long
+-------
+On windows 64bit, sizeof(unsigned long) == 32 and sizeof(size_t) == 64.
+On linux 64bit, sizeof(unsigned long) == sizeof(size_t) == 64
+
+intptr_t and uintptr_t (inttypes.h): ints that guarantee to hold a pointer.
+
+ptrdiff_t: type returned by arithmetic differencing two pointers.
+
+::operator new and ::operator delete
+-------
+[Stroustrup3rd, 19.4.5, p576]
+Can be redefined, to use posix_memalign and free
+The redefinition can be done as class members [Stroustrup3rd, 15.6, p421]
+class A
+{
+    static void* operator new (size_t size);
+    static void operator delete (void *p);
+};
+
+int main()
+{
+    A *p = new A; // calls A::new;
+    delete p; // calls A::delete;
+
+}
+
+The redefinition can't be done on other namespace than the global, if not
+done in a class.
+
+Prototypes for the new/delete Operators
+--------------
+void* operator new(size_t);
+void operator delete(void* );
+void* operator new[](size_t);
+void operator delete[](void* );
+#include <new> // has set_new_handler(), for bad_alloc handling.

+Exceptions
+=================

+
+
+Casting
+=================
+Explicit type conversion [Stroustrup3rd, 6.2.7, p130]
+static_cast - converts between related types (pointer to another, enum to int,
+        float to int,...). Has minimal type checking, and are often portable.
+reinterpret_cast - converts between unrelated types (pointer to int, pointers
+        to functions [7.7], ...).
+        No type checking. Rarely portable. 
+dynamic_cast - run-time checked conversion.
+const_cast - for removing const qualifiers.
+(Type) exp - Unspecified combination of static+reinterpret+dynamic casts,
+        to get the cast done.
