DESCRIPTION

25       The seekdir() function sets the location in the directory  stream  from
26       which  the next readdir(2) call will start.  The loc argument should be
27       a value returned by a previous call to telldir(3).
28

RETURN VALUE

30       The seekdir() function returns no value.

CAVEATS

49       Up   to   glibc  2.1.1,  the  type  of  the  loc  argument  was  off_t.
50       POSIX.1-2001 specifies long, and this is  the  type  used  since  glibc
51       2.1.2.   See telldir(3) for information on why you should be careful in
52       making any assumptions about the value in this argument.
