Hi,
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 POSIX layer does indeed use a form of UTF-8, but the correct
answer here is -fileSystemRepresentation or -
getFileSystemRepresentation:maxLength:, which insulate you from the
need to hard-code the encoding.
Also noted in the reference for this method: "To convert a char *
path (such as you might get from a C library routine) to an NSString
object, use NSFileManager‘s stringWithFileSystemRepresentation:length:
method."
