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
     describing the error.
