JNI: passing bytes from c++ to java

Question

HANDLE hFile = CreateFileA(\"C:\\\\myfile.zip\", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
const int size = GetFileSize(hFile, NULL);
char* buf         


        

Answer 1

I think your missing a line like :

(*env)-> SetByteArrayRegion(env, result, 0, size, fill);
