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;
}
}
