seekdir() -- General Function (libc)

Reset the position within a directory stream
void seekdir (dirp, loc)
DIR *dirp;
off_t loc;

The function seekdir() is one of a set of COHERENT routines that manipulate
directories in a device-independent manner.  It resets the current position
within  the directory  stream pointed  to  by dirp  to loc.  loc must  be a
position indicator returned by a previous call to telldir().

If an error occurs, seekdir() exits and sets errno to an appropriate value.

Notes

telldir() and  seekdir() are unreliable when the  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.
