I am porting an app to Mac OS X (well, actually someone else has
ported it and I am building a cocoa GUI).
I have an NSString with a filename in it that I need to pass to the
portable code as a char *. The portable code will then pass it to
UNIX file handling functions like fopen().
I guess that I need to use NSString's getCString:maxLength:encoding:
method, but what should I pass for the encoding parameter? Phrased
another way, what encoding does fopen() expect filenames to be in?
The correct thing to do would be to use:
-[NSString fileSystemRepresentation]
