| 2 | |
| 3 | # Defines constants and functions for interpreting stat/lstat struct |
| 4 | # as returned by posix.stat() and posix.lstat() (if it exists). |
| 5 | |
| 6 | # XXX This module may have to be adapted for UNIXoid systems whose |
| 7 | # <sys/stat.h> deviates from AT&T or BSD UNIX; their S_IF* constants |
| 8 | # may differ. |
| 9 | |
| 10 | # Suggested usage: from stat import * |
| 11 | |
| 12 | # Tuple indices for stat struct members |
