Just wondering whether it is possible to update a ByteArray in C Code, which is created in Java, without returning it from C.

I have situation, where I need to update a single bytearray for multiple times through JNI and returning bytearray from C takes lot of JNI calls. Please let me know if anybody knows how to do this?

Code should be something like this

Java Code

byte[] storeData;
updateFromNative(storeData); //update the byteArray in native code;
//use the storeData in Java with updated value.
