Have you tried returning a string instead of char? or changing char *s to char s[]
Domanda
I am using Unamanged dependencies (RGiesecke.DllExport.DllExport) and jna in a small C# function that should return a string consumed within another now java function.
Following the jna suggestions for mapping i crafted the code below:
My C# code:
[RGiesecke.DllExport.DllExport]
public static unsafe char* Test(string id)
{
unsafe
{
fixed (char *s = "test passed")
{
return s;
}
}
}
Java side:
public interface ITest extends Library{
public String Test(String id);
}
public static void main(String[] args) {
ITest nativeExample= (ITest)Native.loadLibrary("C:/native/JavaLib.dll", ITest.class);
String s = nativeExample.Test("id");
System.out.println(s);
}
So, all that is printed, is 't', because I bet all is being transmitted is the address to s[0]. Has anyone had luck mapping strings from C# to java through jna?
Plain strings in the C# code throws errors.
