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 const keyword can also be used in pointer declarations. Copy. A pointer to a variable declared as const can be assigned only to a pointer that is also declared as const. Copy. You can use pointers to constant data as function parameters to prevent the function from modifying a parameter passed through a pointer.
