Encoding globally available pointers helps protect them from being exploited. The EncodePointer function obfuscates the pointer value with a secret so that it cannot be predicted by an external agent. The secret used by EncodePointer is different for each process. A pointer must be decoded before it can be used.
The operand of the built-in indirection operator is a pointer to object or function, and the result is the lvalue that the pointer is pointing to. Note that a pointer to incomplete type can be dereferenced, e.g. when initializing a reference.
