Dynamic memory allocation - how is it supported?

The Arduino toolchain uses a full C++ compiler (gcc), so for the most part everything is supported with some exceptions to save memory (No float support in sprintf for example).

The Arduino reference is basic and more focussed on the Arduino specific functions in its library, with a helping of things C++ you will find handy in Arduino coding. Use an actual C++ reference if you need more than this.

So when you write this, you mean the main structure functions of C++ is implemented, and all of them may not be in the Arduino Reference. Class member functions like with String can be quite different with different implementations - is this the right understanding?
