Hello. I'm building a multiplayer game on the iPhone and I need to send string data to the other players in the game. To do that, I need to encapsulate my NSString* string data in an NSData object somehow. Here's an example of how my code is structured...

typedef struct 
{
   PACKETTYPE packetType;
   ??? stringToSend;  //<---not sure how to store this
} StringPacket;    

StringPacket msg;
msg.packetType = STRING_PACKET;
msg.stringToSend = ...  //  <---not sure what to do here
NSData *packet = [NSData dataWithBytes:&msg length:sizeof(StringPacket)];

So my question is, if StringPacket is a struct defined in my header, what type should the stringToSend property be so that I can easily call the dataWithBytes method of NSData to encapsulate the packet data in an NSData object?

Thanks for your wisdom!
