EncodePointer function

Encodes the specified pointer. Encoded pointers can be used to provide another layer of protection for pointer values.

Syntax


PVOID EncodePointer(
  _In_ PVOID Ptr
);

Parameters

Ptr [in]

The pointer to be encoded.

Return value

The function returns the encoded pointer.

Remarks

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.
