| michael@0 | 16 | // 32-bit inodes. There is a getdirentries64 syscall in 10.6, but it's not |
| michael@0 | 17 | // wrapped and the direct syscall interface is unstable. Using an unstable API |
| michael@0 | 18 | // seems worse than falling back to enumerating all file descriptors so we will |
| michael@0 | 19 | // probably never implement this on the Mac. |
