seekdir(3)		    Library Functions Manual		      seekdir(3)

NAME
     seekdir  -	 set  the  position  of the next readdir() call in the directory
     stream.

LIBRARY
     Standard C library (libc, -lc)

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 >= 2.19: */ _DEFAULT_SOURCE
	     || /* glibc <= 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.

HISTORY
     POSIX.1-2001, 4.3BSD.

CAVEATS
     Up to glibc 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  as-
     sumptions about the value in this argument.
