LIBUFS(3) 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 imple- menting 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.
