-.TH READDIR 2 2013-06-21 "Linux" "Linux Programmer's Manual"
-.SH NAME
-readdir \- read directory entry
-.SH SYNOPSIS
-.nf
-.sp
-.BI "int readdir(unsigned int " fd ", struct old_linux_dirent *" dirp ","
-.BI " unsigned int " count );
-.fi
-
-.IR Note :
-There is no glibc wrapper for this system call; see NOTES.
-.SH DESCRIPTION
-This is not the function you are interested in.
-Look at
-.BR readdir (3)
-for the POSIX conforming C library interface.
-This page documents the bare kernel system call interface,
-which is superseded by
-.BR getdents (2).
-.PP
-.BR readdir ()
-reads one
-.I old_linux_dirent
-structure from the directory
-referred to by the file descriptor
-.I fd
-into the buffer pointed to by
-.IR dirp .
-The argument
-.I count
-is ignored; at most one
-.I old_linux_dirent
-structure is read.
-.PP
-The
-.I old_linux_dirent
-structure is declared as follows:
-.PP
-.in +4n
-.nf
-struct old_linux_dirent {
- long d_ino; /* inode number */
- off_t d_off; /* offset to this \fIold_linux_dirent\fP */
- unsigned short d_reclen; /* length of this \fId_name\fP */
- char d_name[NAME_MAX+1]; /* filename (null-terminated) */
-}
-.fi
-.in
-.PP
-.I d_ino
-is an inode number.
-.I d_off
-is the distance from the start of the directory to this
-.IR old_linux_dirent .
-.I d_reclen
-is the size of
-.IR d_name ,
-not counting the terminating null byte (\(aq\\0\(aq).
-.I d_name
-is a null-terminated filename.
-.SH RETURN VALUE
-On success, 1 is returned.
-On end of directory, 0 is returned.
-On error, \-1 is returned, and
-.I errno
-is set appropriately.
-.SH ERRORS
-.TP
-.B EBADF
-Invalid file descriptor
-.IR fd .
-.TP
-.B EFAULT
-Argument points outside the calling process's address space.
-.TP
-.B EINVAL
-Result buffer is too small.
-.TP
-.B ENOENT
-No such directory.
-.TP
-.B ENOTDIR
-File descriptor does not refer to a directory.
-.SH CONFORMING TO
-This system call is Linux-specific.
-.SH NOTES
-Glibc does not provide a wrapper for this system call; call it using
-.BR syscall (2).
-You will need to define the
-.I old_linux_dirent
-structure yourself.
-However, probably you should use
-.BR readdir (3)
-instead.
-
-This system call does not exist on x86-64.

-.BR getdents (2),
-.BR readdir (3)
-.SH COLOPHON
-This page is part of release 3.79 of the Linux
-.I man-pages
-project.
