SYNOPSIS         top

       void seekdir(DIR *dirp, long loc);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

           || /* Glibc since 2.19: */ _DEFAULT_SOURCE
           || /* Glibc versions <= 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.
