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(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE
The seekdir() function returns no value.
The seekdir() function is thread-safe.
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.
