How to get byte array as return from C byte pointer in JNA

Question

I am using JNA for access to native functions. In my native function one my method is returning byte pointer. How could I get same byte array values as return in JNA? I have tried by getting as string and convert it to bytes but it's not working.

This is my code:

BYTE* GetImageDate(); // in C++

Return a pointer, then use Pointer.getByteArray(0, size) to extract size bytes from the corresponding memory location.

Note that you'll have to somehow figure out what size is, unless the function is returning a NUL-terminated C string.
