2461 | Also note POSIX open flags | |
50c2f753 | 2462 | 2) Close - to return the last write time to do cache across close |
87f440e7 | 2463 | more safely |
50c2f753 | 2464 | 3) FindFirst return unique inode number - what about resume key, two |
1982c344 SF |
2465 | forms short (matches readdir) and full (enough info to cache inodes) |
2466 | 4) Mkdir - set mode | |

2467 | |
2468 | And under consideration: | |
1982c344 | 2469 | 5) FindClose2 (return nanosecond timestamp ??) |
50c2f753 | 2470 | 6) Use nanosecond timestamps throughout all time fields if |
1da177e4 | 2471 | corresponding attribute flag is set |
