DIRENT(4) SysV DIRENT(4)
NAME
dirent - file system independent directory entry
SYNOPSIS
#include <sys/dirent.h>
#include <sys/types.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 /* data from readdir() */
{
long d_ino; /* inode number of entry */
unsigned short d_reclen; /* length of this record */
unsigned short d_namlen; /* length of string in d_name */
off_t d_off; /* offset of disk directory entry */
char d_name[1]; /* name of file */
};
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 it will always result in the next entry being on a long
boundary.
