How do I determine the amount of free disk on a volume on OSX 10.4.x? The *nix statfs() API seems limited to 32bit file lengths, unless i'm misunderstanding something. Can someone send me a quick example of how to do this?

[dualg5:~/temp] steve$ cat statfs.c
#include <sys/param.h>
#include <sys/mount.h>
#include <stdio.h>

int main()
{
        struct statfs fs;

        statfs( "/", &fs );
        printf( "%ld, %ld, %lld\n", fs.f_bsize, fs.f_bfree,
               (int64_t)fs.f_bsize*fs.f_bfree );
        return 0;
}
[dualg5:~/temp] steve$ gcc -Wall statfs.c
[dualg5:~/temp] steve$ ./a.out
