seekdir - set the position of the next readdir() call in the directory stream.
#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 versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
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).
The
seekdir() function returns no value.

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