16       seekdir():
17        _XOPEN_SOURCE
18           || /* Glibc since 2.19: */ _DEFAULT_SOURCE

DESCRIPTION

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

RETURN VALUE

27       The seekdir() function returns no value.

NOTES

42       In  glibc  up to version 2.1.1, the type of the loc argument was off_t.
43       POSIX.1-2001 specifies long, and this is  the  type  used  since  glibc
44       2.1.2.   See telldir(3) for information on why you should be careful in
45       making any assumptions about the value in this argument.
