DIRENT(4) 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 {
long 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 it will always result in the next entry being
on a long boundary.
