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.-2008.  

HISTORY

POSIX.-2001, 4.3BSD.  

CAVEATS

Up to glibc 2.1.1, the type of the loc argument was off_t. POSIX.-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.
