// 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.
