Hello,

I wrote a DLL with Borland C and used the Java Native Interface to call
the methods from within Java. One of the parameters in a function in the
DLL is a byte array. I use the function defined in the header file jni.h
to copy elements from a byte array (pointer) in C to the Java byte
array. However, I don't want to copy all the elements from the C array
to the Java array.

In jni.h is defined:
void (JNICALL *GetByteArrayRegion)
(JNIENV *env, jbyteArray array, jsize start, jsize len, jbyte *buf)

How exactly does this function work?
Can I use this function to copy some elements from the C array to the
Java array?
Should I call the release-function afterwards?

Thanks in advance.
