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.

STANDARDS

       POSIX.1-2008.

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.
