LIBUFS(3)		 BSD Library Functions Manual		     LIBUFS(3)

NAME
     libufs -- operate on UFS file systems from	userland

LIBRARY
     UFS File System Access Library (libufs, -lufs)

SYNOPSIS
     #include <sys/param.h>
     #include <sys/mount.h>
     #include <ufs/ufs/ufsmount.h>
     #include <ufs/ufs/dinode.h>
     #include <ufs/ffs/fs.h>
     #include <libufs.h>

DESCRIPTION
     The libufs	library	and the	functions it provides are used for implement-
     ing utilities which need to access	a UFS file system at a low level from
     userland.	Facilities provided are	used to	implement utilities such as
     newfs(8) and dumpfs(8).  The libufs library is designed to	be simple, and
     to	provide	functions that are traditionally useful	to have.

     A disk is represented as the type struct uufsd as defined in <libufs.h>.
     The structure is filled out, operations are performed, and	the disk is
     closed.

ERRORS
     Functions provided	by libufs return -1 in every functional	error situa-
     tion.  They also set the d_error field of struct uufsd to a string	de-
     scribing the error.
