SEEKDIR(3)              Linux Programmer's Manual             SEEKDIR(3)

NAME         top

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

SYNOPSIS         top

       #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 <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE

DESCRIPTION         top

       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         top

       The seekdir() function returns no value.

CONFORMING TO         top

       POSIX.1-2001, POSIX.1-2008, 4.3BSD.

NOTES         top

       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.
