| // This header provides a class, DirReaderPosix, which allows one to open and |
| // read from directories without allocating memory. For the interface, see |
| // the generic fallback in dir_reader_fallback.h. |
| |
| // Mac note: OS X has getdirentries, but it only works if we restrict Chrome to |
| // 32-bit inodes. There is a getdirentries64 syscall in 10.6, but it's not |
| // wrapped and the direct syscall interface is unstable. Using an unstable API |
| // seems worse than falling back to enumerating all file descriptors so we will |
| // probably never implement this on the Mac. |
