JNI and return bool statement problem

[Kacper Lekstan]

This is my first post here so Hello Everyone

I have small (I guess) problem with c++ but its directly connected with JNI... so the problem is: I wrote a program in Java to maintain some kind of hardware box... to do this I had to use JNI because there was no any jar, only one *.lib, so base on lib functions I wrote java class and generete c++ headerer and I created c++ lib to have possibility to use nativ lib. Till this moment everything was fine but i had to return box and now im trying to write some kind of nativ virtual library so I can simulate this box and here is the problem:

JNIEXPORT jint JNICALL Java_test_OpenDeviceDLL(JNIEnv *env, jobject obj, jint CardAddress){

	return OpenDevice(CardAddress);//<--- this works fine
};

JNIEXPORT jboolean JNICALL Java_test_ReadDigitalChannelDLL(JNIEnv *env, jobject obj, jint Channel){

	return ReadDigitalChannel(Channel);  //<--- here is problem because it always return TRUE
};

 extern "C" __declspec(dllexport)

 int OpenDevice(int param) {

	 return 1234567890;
 }

 extern "C" __declspec(dllexport)

 bool ReadDigitalChannel(int param){

	 return FALSE;
 }

as I marked higher return of ReadDigitalChannel(Channel); is always true no matter what I put into its body

thank you for any tips/solution/clue

Regards

SOLUTION

the simplest answer is: C have no bool statement so changing return type into int solving problem
