int readdir(unsigned int fd, struct old_linux_dirent *dirp, unsigned int count);
DESCRIPTION
This is not the function you are interested in.
Look at
readdir(3)
for the POSIX conforming C library interface.
This page documents the bare kernel system call interface,
which is superseded by
getdents(2).
readdir()
reads one
old_linux_dirent
structure from the directory
referred to by the file descriptor
fd
into the buffer pointed to by
dirp.
The argument
count
is ignored; at most one
old_linux_dirent
structure is read.
The
old_linux_dirent
structure is declared as follows:
struct old_linux_dirent {
long d_ino; /* inode number */
off_t d_off; /* offset to this old_linux_dirent */
unsigned short d_reclen; /* length of this d_name */
char d_name[NAME_MAX+1]; /* filename (null-terminated) */
}
d_ino
is an inode number.
d_off
is the distance from the start of the directory to this
old_linux_dirent.
d_reclen
is the size of
d_name,
not counting the null terminator.
d_name
is a null-terminated filename.
RETURN VALUE
On success, 1 is returned.
On end of directory, 0 is returned.
On error, -1 is returned, and
errno
is set appropriately.
ERRORS
EBADF
Invalid file descriptor
fd.
EFAULT
Argument points outside the calling process's address space.
EINVAL
Result buffer is too small.
ENOENT
No such directory.
ENOTDIR
File descriptor does not refer to a directory.
CONFORMING TO
This system call is Linux-specific.
NOTES
Glibc does not provide a wrapper for this system call; call it using
syscall(2).
You will need to define the
old_linux_dirent
structure yourself.
This page is part of release 3.14 of the Linux
man-pages
project.
