GETDIRENTRIES(2):
"As of Mac OS X 10.6, getdirentries() is deprecated, and it is recommended
 that applications use readdir(3) rather than using getdirentries() directly.
 Due to limitations with the system call, getdirentries() will not work with
 64-bit inodes; in order to use getdirentries(), _DARWIN_NO_64_BIT_INODE must
 be defined."
