READDIR(2)		   Linux Programmers Manual		   READDIR(2)



NAME
       readdir - read directory entry

SYNOPSIS
       #include 
       #include 

       int readdir(unsigned int fd, struct 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       kernel system call interface, which can change, and which is superseded
       by getdents(2).

       readdir() reads one dirent structure from the directory referred to  by
       the  file  descriptor fd into the buffer pointed to by dirp.  The argu
       ment count is ignored; at most one dirent structure is read.

       The dirent structure is declared as follows:

	   struct dirent {
	       long	d_ino;		     /* inode number */
	       off_t	d_off;		     /* offset to this 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 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 processs 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).
