iOS Plugins - Sending string parameters

Unity Engine

Is it possible to send string data to a C plugin from Unity? If so what type should the C script be expecting?

Im currently using the following:

[DllImport ("__Internal")] 
public static extern void ActivateTutorial( string description );

and the C Script:

extern 'C'
{
    void ActivateTutorial(  what magical type goes here? Im assuming char *  );
}

Quick Bump?

I use “const char*” and then copy into local buffer.

So it looks something like this:

#define _BUF_SIZE 128

static char _description[ _BUF_SIZE ];

extern "C" void ActivateTutorial( const char* description )
  {
  strncpy( _description, description, _BUF_SIZE ); 
  . . .
  }

Hi

On the XCode side it might (don’t quote me on this) but it could be:

void ActivateTutorial(  char *  myString )
{
    // do something with your string in here
}

or

void ActivateTutorial(const char *  myString )
{
    // do something with your string in here
}
