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 assumptions about the value in this argument.
