I need to be able to save the player's progress in the game. What is the preferred way of creating directories under OSX? I would prefer a C++ solution to this but if it has to be Cocoa then so be it. My basic assumption at this point is that it should be saved to ~/Library/Application Support/<game name> but how in code can you create a directory at that location?

For the POSIX way, man 2 mkdir

mkdir man page Wrote:#include <sys/stat.h>

int
mkdir(const char *path, mode_t mode);

For the Cocoa way, see NSFileManager

NSFileManager documentation Wrote:- (BOOL)createDirectoryAtPath:(NSString *)path withIntermediateDirectories:(BOOL)createIntermediates attributes:(NSDictionary *)attributes error:(NSError **)error

Also Cocoa:

I was using mkdir already so I guess I will stick with it.

Thanks for the reassurance.
