dirent(4) —
NAME
dirent − file system independent directory entry
SYNOPSIS
#include <dirent.h>
DESCRIPTION
Different file system types may have different directory entries. The dirent structure defines a file system independent directory entry, which contains information common to directory entries in different file system types. A set of these structures is returned by the getdents(2) system call.
The dirent structure is defined below.
struct dirent {
ino_t d_ino;
off_t d_off;
unsigned short d_reclen;
char d_name[1];
};
The d_ino is a number which is unique for each file in the file system. The field d_off is the offset of that directory entry in the actual file system directory. The field d_name is the beginning of the character array giving the name of the directory entry. This name is null terminated and may have at most MAXNAMLEN characters. This results in file system independent directory entries being variable length entities. The value of d_reclen is the record length of this entry. This length is defined to be the number of bytes between the current entry and the next one, so that the next structure will be suitably aligned.
