Assuming the function is defined (and I'm not going to google that name from work), you have a problem with the way you're printing it:

cout << "%10.10s", sperm(statbuf.st_mode);

That's not going to print a formatted string, since C++ iostreams don't work like C's printf. You could either not format it:

cout << sperm(statbuf.st_mode);

or use printf:

printf("%10.10s", sperm(statbuf.st_mode));

or do some jiggery-pokery with iostream manipulators.
