Optimized C++ Code for Generating PGN from Game Data

jbyteArray getPGN(JNIEnv* env) { GAME_LOADED;

TextBuffer tbuf;
tbuf.SetBufferSize(TBUF_SIZE);
tbuf.Empty();
tbuf.SetWrapColumn(99999);

game.WriteToPGN(&tbuf);

const char* pgnBuffer = tbuf.GetBuffer();
int length = strlen(pgnBuffer);

jbyteArray result = env->NewByteArray(length);
env->SetByteArrayRegion(result, 0, length, reinterpret_cast<const jbyte*>(pgnBuffer));

return result;
