Re: Cocoa string to carbon compatible C string

Thanks for the info, the deal is I don't have access to the source for 
'initSomeSystem'.
So I can't answer your question, other than to point out what does 
work..
I do know that ' #define kVersion "abc" ' creates a suitable string.

I'm trying to do the 'best' substitution I can with the fact that I 
have an NSString and no access to the called method.

Hence my original question as the result of a #define x "123" being a 
'char*'.
If that is true, then is the following the best solution?

   #define kVERSION "abc"
   NSString * partNumber = [[blah blah] moreBlah];
.....
   const char *  cPartNumber = [partNumber 
cStringUsingEncoding:NSUTF8StringEncoding];
   if( (p_flag = initSomeSystem (
                   kVERSION,             
                   (char *) cPartNumber,
                   &errorCode))
         == NULL) { ....

Thanks,
Steve
