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 encoder is a measurement device which converts mechanical motion into electronic signals.

The code shown pictured above shows a typical use of an encoder.
