[Mono-list] What is Correct way to marshal wchar_t ?

[ptr2009]

hey all

 I am trying to marshal strings from managed code to native code using
DllImport. Marshalling both wchar_t* and char* works under mono on a windows
box. 

But on mac os x wchart_t marshalling does not seem to work. The wchar_t* is
all junk. I have tried to search this forum and people have talked about it
and it seems to have been fixed.

Am I missing something ? I have experimented with CharSet.Unicode on
DllImport and it still doesnt work ?

What is the recommended way ?

Thanks
Raj



My cs files is something like this
____________________________________________
[DllImport("Test.dll", EntryPoint = "Global_PrintStringW")]
 public static extern void Global_PrintStringW(
[MarshalAs(UnmanagedType.LPWStr)]string arg1);

[DllImport("Test.dll", EntryPoint = "Global_PrintStringA")]
 public static extern void Global_PrintStringA(string arg1);


        private static void StringMarshallingTest()
        {
           
            string newString = "This is a cool string";

            Console.WriteLine("Global_PrintStringA Test ");
            Global_PrintStringA(newString);

            Console.WriteLine("Global_PrintStringW Test ");
            Global_PrintStringW(newString);
     
        }

My cpp file is something like this
________________________________

extern "C"
{
	EXPORT_API void Global_PrintStringW(const wchar_t * str)
	{
		std::wcout << "Global_PrintStringW called with " << str << std::endl;
	}

	EXPORT_API void Global_PrintStringA(const char* str)
	{
		std::wcout << "Global_PrintStringA called with " << str << std::endl;
	}
}
