This is a compile time option. 271.Pp 272The behaviour of 273.Fn telldir 274and 275.Fn seekdir 276is likely to be wrong if there are parallel unlinks happening 277and the directory is larger than one page. 278There is code to ensure that a 279.Fn seekdir 280to the location given by a 281.Fn telldir 282immediately before the last 283.Fn readdir 284will always set the correct location to return the same value as that last 285.Fn readdir 286performed. 287This is enough for some applications which want to "push back the last entry read" E.g. Samba. 288Seeks back to any other location, 289other than the beginning of the directory, 290may result in unexpected behaviour if deletes are present. 291It is hoped that this situation will be resolved with changes to 292.Fn getdirentries 293and the VFS. |
