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.
(C++ provides a slightly simpler interface with JNI.) When the JVM invokes the function, it passes a JNIEnv pointer, a jobject pointer, and any Java arguments declared by the Java method. A JNI function may look like this: The env pointer is a structure that contains the interface to the JVM.It includes all of the functions necessary to interact with the JVM and to work with Java objects.
