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]
