// 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.
