NAME
     fstyp_mod_init,       fstyp_mod_fini,       fstyp_mod_ident,
     fstyp_mod_get_attr,  fstyp_mod_dump - libfstyp module inter-
     face

SYNOPSIS
     cc [ flag... ] file... -lfstyp  -lnvpair  [ library... ]
     #include 
     #include 

     int fstyp_mod_init(int fd, off64_t **offset, fstyp_mod_handle_t *handle);


     void fstyp_mod_fini(fstyp_mod_handle_t handle);


     int fstyp_mod_ident(fstyp_mod_handle_t handle);


     int fstyp_mod_get_attr(fstyp_mod_handle_t handle, nvlist_t **attr);


     int fstyp_mod_dump(fstyp_mod_handle_t handle, FILE *fout, FILE *ferr);


PARAMETERS
     fd        Open file descriptor of a block or  a  raw  device
               that contains the file system to be identified.


     offset    Offset from the beginning of the device where  the
               file system is located.


     handle    Opaque  handle  that   the   module   returns   in
               fstyp_mod_init()  and  is  used  with other module
               functions.


     fout      Output stream.


     ferr      Error stream.


DESCRIPTION
     A libfstyp module implements heuristics required to identify
     a file system type. The modules are shared objects loaded by
     libfstyp. The libfstyp modules are  located  in  /usr/lib/fs
     subdirectories.  A subdirectory name defines the name of the
     file system.

                                           fstyp_mod_init(3FSTYP)



     Each module exports the fstyp_mod_init(),  fstyp_mod_fini(),
     fstyp_mod_ident(),  and  fstyp_mod_get_attr() functions. All
     of these functions map directly to the  respective  libfstyp
     interfaces.


     The fstyp_mod_dump() function is optional. It can be used to
     output  unformatted  information about the file system. This
     function is used by the fstyp(1M) command when the -v option
     is  specified.  The  fstyp_mod_dump() function is not recom-
     mended and should be used only in legacy modules.

FILES
     /usr/lib/fs/

         Default module directory.


     /usr/lib/fs/fstype/fstyp.so.1

         Default path to a libfstyp module  for  an  fstype  file
         system.
