SEEKDIR(3)                 Linux Programmer's Manual                SEEKDIR(3)
NAME
       seekdir  - set the position of the next readdir() call in the directory
       stream.
SYNOPSIS
       #include <dirent.h>
       void seekdir(DIR *dirp, long loc);
   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
       seekdir():
        _XOPEN_SOURCE
           || /* Glibc since 2.19: */ _DEFAULT_SOURCE
           || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
DESCRIPTION
       The seekdir() function sets the location in the directory  stream  from
       which  the next readdir(2) call will start.  The loc argument should be
       a value returned by a previous call to telldir(3).
RETURN VALUE
       The seekdir() function returns no value.

CONFORMING TO
       POSIX.1-2001, POSIX.1-2008, 4.3BSD.
NOTES
       In  glibc  up to version 2.1.1, the type of the loc argument was off_t.
       POSIX.1-2001 specifies long, and this is  the  type  used  since  glibc
       2.1.2.   See telldir(3) for information on why you should be careful in
       making any assumptions about the value in this argument.
