telldir() -- General Function (libc) Return the current position within a directory stream off_t telldir (dirp) DIR *dirp; The COHERENT function telldir() is one of a set of COHERENT routines that manipulate directories in a device-independent manner. It returns the current position within the directory stream pointed to by dirp. If an error occurs, telldir() exits and sets errno to an appropriate value. See Also closedir(), dirent.h, getdents(), libc, opendir(), readdir(), rewinddir(), seekdir(), Notes The value returned by telldir() should only be used as an argument to seekdir(). telldir() and seekdir() are unreliable when directory stream has been closed and reopened. It is best to avoid using telldir() and seekdir() altogether. Because directory entries can dynamically appear and disappear, and because directory contents are buffered by these routines, an application may need to continually rescan a directory to maintain an accurate picture of its active entries. The COHERENT implementation of the dirent routines was written by D. Gwynn.
