Miklos Szeredi | ab97456 | 2005-04-07 15:40:21 +0000 | [diff] [blame] | 254 | * 1) The readdir implementation ignores the offset parameter, and |
| 255 | * passes zero to the filler function's offset. The filler |
| 256 | * function will not return '1' (unless an error happens), so the |
| 257 | * whole directory is read in a single readdir operation. This |
| 258 | * works just like the old getdir() method. |
| 259 | * |
| 260 | * 2) The readdir implementation keeps track of the offsets of the |
| 261 | * directory entries. It uses the offset parameter and always |
| 262 | * passes non-zero offset to the filler function. When the buffer |
| 263 | * is full (or an error happens) the filler function will return |
| 264 | * '1'. |
