    NAME

    
    
    libufs
    
     - operate on UFS file systems from userland
    
     
    

    LIBRARY

    Lb libufs
    
     
    

    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 library and the functions it provides are used for implementing 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 library is designed to be simple, and to provide functions that are traditionally useful to have.

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

    ERRORS

    Functions provided by return -1 in every functional error situation. They also set the d_error field of Vt struct uufsd to a string describing the error.
