The question is: Suppose I use the function: (* env) -> GetByteArrayRegion (env, array, 0, len, (jbyte *)buf); In this case, a certain number of bytes written from the array to the buf or vice versa? Maybe a simple question, but I'm confused. Help, please:. In the documentation is not found.
Get <PrimitiveTypeArray>ArrayRegion is a family of functions that copies a region of a primitive array into a buffer. That's what the documentation says. It seems clear to me.
