when I ran the program.

It happened at code (Pointer) args.createArray().

But the java and native side programs were compiled successfully.

Is there a way to avoid this?

Thanks in advance.

I get a similar error:

An unexpected exception has been detected in native code outside the VM.

Unexpected Signal : EXCEPTION_ACCESS_VIOLATION (0xc0000005) occurred at PC=0x184




NOTE: We are unable to locate the function name symbol for the error

     just occurred. Please refer to release documentation for possible

     reason and solutions.

I get this error after calling the following C function multiple times (30+):

int32 pipt_tag(int32 pt, char PIPTR * tag, int32 len );


pt (passed) Point number

tagname (returned) Tagname buffer

len (passed) Length of the passed tagname buffer

With the following java code

private static long charlength = 40;


     xFunction pipt_tag = new xFunction("piapi32", "int pipt_tag(int, CSTRING, int)");

     String tag = "";

     int pt = point.getPointnumber();

     Argument[] args = new Argument[3];

     args[0] = new Argument(pt);

     args[1] = new Argument(tag, Argument.CSTRING);

     args[2] = new Argument(charlength);


      tag = (String) args[1].getValue();

If I make this call once or twice, the error does not occur. It only occurs, when it is called multiple times

Thanks in advance,
