#include <dirent.h>
void seekdir(DIR *dirp, long loc);

|| /* glibc <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
DESCRIPTION

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.
